  1. Day 18 Flower

    PH 5.5

    PPM 820

    Humidity 50%

    Temps 19 Degrees lights off - 24 Degrees lights on

    Water Temps 20 degrees

    Changed out the nutrients today and trying something different, below if the feeding they got this time around.

    Silica 25ml

    Cal Mag 10ml = 150ppm

    Micro 10ml = 145ppm

    Diamond Nectar 8ml

    Grow 2ml = 30ppm

    Bloom 13ml = 100ppm

    PK 13/14 3ml = 35ppm

    Super Thrive few drops

    4ml ph down

    Starting ppm 360

    Total 820ppm

    Starting ph 7.3

    Finished ph 5.5

    Plants look really happy but bud production looks a little behind for this stage of the game, doesn't help that I don't know which strains I'm dealing with and if they are early or late finishers.
    The leds are now lowered to 12 inches from the canopy and the plants are showing no signs of light burn, I'm hoping the pk 13/14 kicks bud production into overdrive but let's see what happens.

    Overall I'm very pleased with how my first hydro grow is going, I was expecting it to be a hell of a lot more complicated than it is.


    thanks for looking















  2. Day 13 of flower

    PH: 5.8

    EC: 1.6 or 800 PPM

    Humidity: 53%

    24 degrees lights on - 19 degrees lights off.

    Water Temps: 20 degrees

    Ok so I'm 13 days into flower now and still no signs of any of the 3 plants showing their sex, no white pistols at all.
    This has me a bit concerned and the only thing I could think of doing was adjusting my light timer so lights on will be 11 hours 45 minutes and lights off will be 12 hours 15 minutes.... hopefully this will move them along a bit faster.

    I decided not to change the nutes out for another week as my EC was raising and the plants didn't take up much nutrients. In one week the EC has raised from 1.5 to 1.8, my next nutrients change I'm going to drop the EC to 1.3 or 1.4 and see if this fixes the problem of my EC raising.

    For this week I plan on dropping the EC slowly by adding just plane tap water PH'd to 5.3 until I find the sweet spot where my water levels are dropping and EC stays around the same.

    I have narrowed the strains down to either Shiva Skunk or Skunk Kush or maybe even both. 

    Overall I'm happy with growth and they seem to be happy enough for now, over the next week I'll open them up a bit and remove some leaves for better light penetration and do some lst on them.

    Any advice welcome. 

    Thanks for looking. 











  3. Day 7 of flower


    PH 5.3

    EC 1.5

    Temps 23 degrees 

    Humidity 58%

    Water temps 20 degrees 


    Just changed out the nutrients into 20 litre buckets and switched over to bloom mix, still no sign of pre-flowers at day 7. 


    Dropped the PH to 5.3 for this nute change and I will let it steadily rise to 6.2 before adjusting back down.....hopefully this will give the plants a good range of nutrients at different ph levels. 


    I was having some issues with EC and PH rising and water levels dropping before the last nutrient change, I'm guessing this in down to my nute mix being to strong and the plants are taking up water faster than nutrients but maybe I'm wrong.  Hopefully some experienced hydro growers can point me in the right direction regarding this?


    My understanding is EC levels should be dropping as the plants feed, I lowered the EC to 1.5 and I'm hoping this fixes the problem.


    Feeding mix for this nute change is as follows.

    General Hydroponics Flora Series 

    Per 12 litres of water or 3 gallons 

    9ml Grow

    9ml Micro 

    15ml Bloom 

    32ml silica

    0.5ml Super Thrive

    Tap water starting at 0.7 EC or 350 PPM 

    Total EC 1.5 or 750 PPM 

    I'm waiting on a delivery of Cal Mag and Diamond Nectar which I will also be adding, I would like to add B52 by Advanced Nutrients but it's out of my price range at the moment so any suggestions on something similar would be great.


    The two Mars Hydro 300w lights have been lowered to 18 inches from the canopy and the plants are really starting to bush out now. 


    Thats it for now, if anyone has any ideas about the issues above I would greatly appreciate it.

    hello crentz !

    it is difficult to see exactly the problem with the purple light but with you said i think you're right. more, if you solve it with adding epsom salt you was  totally right .

    it's cool to see that. . i hope it will be the last problem for you man !

    continue to read and observe your plants like that.

    I have found that growing in Hydro is very finicky so far and unless you have everything dialled in to nearly 100% like environment/nutrients then things can go wrong very fast....growing style and the way you problem solve also play a big factor in it too. 

    I deliberately used the feminised mix seeds for this grow as a test run so I can have optimal conditions for my second hydro grow, I'm still having some small issues like EC and ph rising while water levels are dropping which I will post in more detail soon here and I am hoping some experienced hydro guys can point me in the right direction on how to correct this. 


    @slimkush thanks for the advice and help it's always appreciated man?

  5. @slimkush I was getting some yellowing of the leaves with the veins staying dark green, the Epsom Salt cured this problem and some of the purpling of the stems but not all of it?

    @Cannabissapean thanks man?


    I'm going to add hydroguard,Cal Mag, Bio-root and Diamond nectar to my feeding schedule this week once I receive delivery and add everything in the order below.

    Cal mag 
    Diamond nectar 


    I wasn't going to do any lst training or super cropping on these girls but decided to start yesterday, plant 2 has now been super cropped as it was starting to stretch a good bit and I'm just doing some light bending of branches on the other two plants. 

    Plant 1 and 3 has 7 tops and plant 2 has 8 tops.

  6. Day 2 of flower

    PH 6.1

    EC 1.6

    Humidity 40%

    Temps 25 to 20 degrees lights on/off

    Water temps 17 to 20 degrees 

    Still on Veg feeding schedule for the first week of flower.


    So I finally solved the problem why the lower leaves were wilting and dying off, it seems my root zone was getting colder than it should be at lights off causing the plants to go into shock and lockout nutrients. 

    I removed about 5 of the really bad leaves and everything is doing a lot better now.

    Only issue now is a small bit of purpling of the leaf stems, I think this a calcium issue even though I have very hard water with an EC of 0.6 and have ruled out a magnesium issue as I've been adding Epsom salt. 

    Haven't done any training on these as I don't see them getting huge in height, all 3 have really bushed out since being topped and plant 2 looks like it will be the most impressive in a few weeks....this one is the only plant with no issues yet and just keeps growing and growing. 

    Next week I will be putting these into 20 litre buckets and hopefully I will have a trouble free grow from here on in?

    Learning a lot from this first Hydro grow and thanks to everyone that took the time to post here and help me out... much love?

    hello i undertand your caution and you're right because a lack of nutrients is more easy to solve than an over feeding with burns.  

    otherwise your new leaves are beautiful and look to accept your mixture.

    continue man +1 for you

    The damage to the affected leaves seems to be still spreading after the nute change, not sure if this is normal. 

    I'm just keeping an eye on newer growth to make sure it's not spreading to these.

    1. hello crentz !!
    2. yes good idea to flush it and then give it at half strenght. do  you flush with clear water or with florakleen or something like that ?
    3. For NFT i just can say : GO !!  I have NFT NUTRICULTURE gt205i with 20-25 L tank. i like this system. After it will be interesting to see the difference between DWC and NFT.
    4. Finally for your babies after your flush and half feeding , i think you could increase your EC a little if your plants can bear it.
    5. continue man and you will be happy soon !
    6. bye

    I'm just flushing with normal tap water with an EC 0.6, they have been flushing now for 48 hours and the new growth seems healthy. 

    As you can see from the pic below I think I over did it with the nutrients and some of the lower leaves got some bad nute burn, I mixed up a batch of nutes last night at half strength and let them sit then ph'd today to 5.8... I will check the ph again before changing out the nutes today. 

    Yeah unfortunately I don't know what strains I'm growing and these plants don't seem to be heavy feeders so I will proceed with caution when upping the EC in future.

    hello my friend !

    i am agree with cannabissapean because i use powder feeding in NFT and ph is really more stable . then i use 3 ACID DOWN of HYDROPASSION and itis a good ph down.

    More , you will earn much time and money with powder feeding ( i use hybrids version) because you don't need to put 2 or 3 products. it is easy to use and it's efficient.

    i recommand you this.

    otherwise your plants are beautiful !!! keep on doing this.

    i can also help you for your humidity. if humidity is too low you can put in your box a humidifier 1 head OR you put some clean wet towels or clothes in order to increase your humidity room.

    if i can help you to another way you're welcome !

    bye BRO !!

    Thanks for the info man, yeah definitely want to try the powder feeding at some stage. 

    I've had my eye on a little 20 litre nft system and would like to try it out on my next grow and do a side by side test grow against the DWC and see what comes out better. 

    I flushed the plants for 24 hours and they seem to be doing a lot better now, I will leave them flushing overnight and do a nute change in the morning at half strength.

    pH rise in the reservoir is normal, just gotta keep adjusting back down every day or so.  pH swing can be beneficial because some nutrients are better absorbed by the roots at various other pH values.


    Using Powderfeeding will usually reduce the wild pH swings, and allows a more stable pH.


    Using the right pH-adjustment solutions will also aid to stabilize pH.  A stable set is from Advanced Hydroponics.  They offer a pH-UP, and they offer two pH-Downs (one is Nitric-Acid-base, for use during Vegg, and the other is Phosphoric-Acid-base, for use during flowering.

    Checked them again this morning and some of the bottom leaves were dying off....turning brown and wilting. 

    Looks like I got nute lock out or some deficiency after my last nute change, it was spreading from the bottom of the plant upwards and some of the leaves started getting pale green in places.

    Freaked me out a bit, I'm flushing them since this afternoon with just plain tap water ph'd to 5.8 and they seem to be bouncing back now. 

    My last nute change I gave them 12ml grow, 6ml micro, 3ml bloom per 4 litres of water, tap water EC is 0.6 starting off, total EC 1.7, The only thing I can think of why this happened is I usually add micro/grow/bloom in that order but forgot to do this on this nute change and added it grow/micro/bloom... I've read in the past not adding micro first can lock out nutrients this coupled with the fact my ph shot up to 6.7 I'd say didn't help matters much. 

    Tomorrow I'm going to half the nutes for the last week of veg 6ml grow, 3ml micro, 2ml bloom, 3ml silica and 1tsp Epsom salt per 4 litres of water. 


  11. Plant #1, 37 days old

    Plant #2, 31 days old 

    Plant #3, 31 days old


    PH 5.8

    EC 1.7

    Humidity 35% 

    Temps, 18 degrees lights off - 24 degrees lights on. 

    Water temps 20 degrees. 


    Changed the nutrients out yesterday with a ph of 5.8 and when I checked today the ph had raised to 6.7 so everything is looking a bit sad at the moment......first time adding silica to my nutes which could be the problem, my tent yesterday started to really stink so I finally hooked up my carbon filter. 


    Still struggling with the humidity because my extraction fan is sucking it all out so if anyone has any suggestions that would be great. 

    Think I'm just gonna give these one more week in Veg before I flip to Flower as I don't like not knowing what strains I'm dealing with and want to move on quickly, plant 3 has bounced back really good now and has the thickest stem of all 3 plants. 

    Anyways that's it for now.

    Thanks Crentz!


    I sent an email, but only with my address.


    My store owner will not give me permission to disclose his address, especially for any product sent from the U.S.A.


    Had you obtained permission from your local head-shop owner?

    No I just gave the address of my friends work, hopefully this will do?

  13. Plant #1, 33 days old 

    Plant #2, 27 days old

    Plant #3, 27 days old

    PH 5.9

    EC 1.7

    Humidity 45%

    Temps 20 degrees 

    Changed the nutes out 4 days ago and raised the EC to 1.7 and added some Epsom salt , the leaf curling problem was a heat issue and was fixed by raising the lights and moving the radiator further away from the plants.

    All plants have now been topped and I plan on vegging for at least another 2 to 3 weeks before flipping into flower, struggling a bit to keep the humidity in the 60% range and have added trays of water into the tent but might need to invest in a humidifier.

    Apart from the slow growth at the start I am really happy how my first hydro grow is turning out, plants are looking really healthy and I'm impressed with the two 300w Mars Hydro led lights.

    Small and squat is not necessarily a bad trait.  Many Indicas grow with very short internodal distances.  Some growers prefer that, especially when available height for growth is limited.  If they continue to have a short internodal distance, then most likely you are growing Indicas or Indica-dominant strains.


    Went back to read this topic from the start:  Package was "Sensi Seeds Feminized Mix" and the strains were not identified, so it could very well be that all the seeds are the same strain.  But IMHO, that's still a fair deal.  Similar to Forrest Gump's saying, "Life is like a box of chocolates; you never know what you're gonna get.", You never know what you might get in a Mix-Pack of unidentified strains.


    I do know this:  Greenhouse Seeds does identify their seeds in mix-packs with a colored coating.


    Your plants are looking very nice.  Enjoy cultivating your Indicas.



    Thanks man

    Bit concerned about speed of growth considering how old these plants are now, humidity and temperatures are all fine so the only thing I'm thinking is a ph issue. 

    I'm using a cheap ph pen but I've checked the calibration and its fine, water temps are 20 degrees, EC 1.2. 

    Another thing that is strange is this is meant to be a feminised mix but all three plants look like the same strain?

    Think I'm going to add a silica additive to be mix to see if it helps with growth, I'm wondering if this strain is just small and squatty by nature. 




  16. 13 hours ago, Cannabissapean said:

    Could be an occasional mutation.  I wouldn't be concerned about it.  Just continue to observe.  It should cause no alarm unless it continues to occur on more of the leaves.


    If it is isolated to just this one leaf, then eventually the leaf will die of old age, and the plant will suck the life out of it.  It will eventually fall off, or you could pluck it off at that time.  No biggy.


    If it expands with little tiny trails, then that is leaf-miners; you'd have to fight them with sprays on the underside and top side of the leaves.  But I see no trails now.

    Thanks for the advice,

    yeah it's just one leaf, strange how I got one leaf the same on another plant though. 

  17. Plant 1, 28 days old

    Plant 2, 22 days old

    Plant 3, 22 days old

    PH 5.8

    EC 1.2

    Humidity 58%

    Temp 20 degrees 


    Plants have really started to grow since the roots hit the water number 3 is still way behind but I'm hoping it catches up, number 1 got topped today and I will top number 2 week. 

    I think my biggest mistake this grow was starting in 1 inch rockwool cubes then transplanting to 3 inch cube, next time I'll go from 1 inch cubes straight into DWC. 

    I haven't changed the nutes in two weeks because the plants were not drinking much so I'll change them out tomorrow and keep the EC at 1.2 and add a little Epsom salt to each bucket, purple stems disappeared when the roots hit the water so it must have been some kind of nutrient deficiency. 

    Getting some of the leafs curling up and not sure if it's a heat of ph problem.

    Plan on vegging these for a good while so I can fill the 4x4 tent as much as possible.

    Plant 2, 16 days old 

    Plant 3, 16 days old

    Temps 20 degrees 

    Humidity 65%

    EC 1.2

    PH 5.9

    Girls are still a little small as I'd like for this stage I'm thinking due to starting their life's out under shitty T8 4000k bulbs I got cheap and I think I maybe over did it with the super Thrive starting out, plant 3 is still way behind after the seed casing issue but seems to be bouncing back now. 


    Roots only dropped into the water on plant 1 today and no visible signs of roots in 2 and 3 yet, going to hold off on changing the nutes for one more week as they haven't really been drinking that much.  

    Noticed a tiny bit of leaf burn on one of the lower leafs but gonna leave the EC at 1.2 for now and if it gets worse I'll drop to 1.0, other than that they're loving  the mars hydro 300w and I'll turn on the second one tomorrow, I'm still thinking plant 1 maybe sativa and 2 and 3 indica but could be wrong?

    anyways that's it for now, thanks for looking?
