Animal351 48 Posted February 19, 2014 Share Posted February 19, 2014 Hi firefighter, yeah I reckon you could be right, are they having any other symptoms such as weak stems and slow growth?Hope you get your girls sorted soon Animal Quote Link to comment Share on other sites More sharing options...
nicc1976 155 Posted February 19, 2014 Share Posted February 19, 2014 You could try a bit off cal mag if you have it I have had similar problems in the past and put a bit off calmag are you in soil or hydro Quote Link to comment Share on other sites More sharing options...
zub0 249 Posted February 19, 2014 Share Posted February 19, 2014 hi firefighterto me it looks like it could be manganese deficency wich is very common when growing indoors.solutions for manganese deficency is often lowering ph , flushing soil and adding new nutes.best wishes 1 Quote Link to comment Share on other sites More sharing options...

No slow growth, no. So what about the calcium? Quote Link to comment Share on other sites More sharing options...
nicc1976 155 Posted February 19, 2014 Share Posted February 19, 2014 I would do what zubo said give them a good flush it can help in so many ways good luck you wont need it Quote Link to comment Share on other sites More sharing options...
zub0 249 Posted February 20, 2014 Share Posted February 20, 2014 reason could be ph is to high for roots to take up manganese . best ph is under 5,8 in hydro and 6-6,5 in soil for manganese uptake best regards to ur garden Quote Link to comment Share on other sites More sharing options...
Jose.gh 8,545 Posted February 20, 2014 Share Posted February 20, 2014 The problems of calcium and magnesium are very similar, the problem is, that if you use a lot of calcium, have a magnesium problems. If you use a lot of magnesium, have a calcium problems .... that always happens. If these problems happen, the best solution is to make a washing roots.If you cultivate marijuana strains of "white" family, eg White Widow, GWS, etc .... is definitely a problem of magnesium. All strains with genetic White, have that problem. Therefore, hybrid powder feeding brings extra magnesium. regards! 4 Quote Link to comment Share on other sites More sharing options...

It is your White Widow and I am using Cal Green, so there should be enough mag and cal in a balanced formula. I am growing in high quality garden soil this time, because White Widow likes soil very much. There she becomes very green. PH is around 6.0 bcause it is soil.This abnormality shown in the leaves only affects some plants, 90% are doing well.I am truely thinking about changing to your hybrid powder feed..........in my motherplants powder feed is doing excellent 1 Quote Link to comment Share on other sites More sharing options...
jankahar 599 Posted February 20, 2014 Share Posted February 20, 2014 it does look like calcium problem to me zubo with manganese there should also be yellowing from inward before the spotting,the initial problem seems to come from the nutrient profile you use 10-40-20 and the possibly from the low ph, in soil recommended ph is between 6.3-6.8 and cal and mg are more available the higher you go in scale you said you have Metrop MR1 and Calgreen, the metrop mr1 has 10-40-20 npk ratio 1.5%mg. and cal green has 15% N , 22.5% cal and 3%mgthe npk ratio seems to be way off to be used alone with calgreen the K should be in highest amount of all 3 nutrients and calcium/magnesium ratio should be around 3/1 or 2/1 but the metrop has 5/1 ratioalso high amount of phosphorous in the mr1 can make insoluble bonds with the calcium if you mix the mr1 first and second calgreen. you should always mix calcium first properly and never over 200ppms or these bonds start to happen in the nutrient solution so you might have a phosphorous build up in the soil atm from mr1's npk ratio that could be making these bonds with calcium every time you try to water it with more calcium and even more P, in this case flushing the roots would be needed first to get rid of the buildup P and get npk ratio to more normal level like 3-2-4 or even just 1-1-1. there should never ever be more P than N or K 2 Quote Link to comment Share on other sites More sharing options...
zub0 249 Posted February 20, 2014 Share Posted February 20, 2014 yes i agree jankahar but i seen yellowing come after spots before and the leaf not in direct light looks to me to be yellowing thats why i think it could be manganese. but j have seen more of this then me for sure funny how all these charts have diffrent ph values as range Quote Link to comment Share on other sites More sharing options...
firefighter 137 Posted February 20, 2014 Author Share Posted February 20, 2014 it does look like calcium problem to me zubo with manganese there should also be yellowing from inward before the spotting, Are you sure Metrop doesn't know this? This is a professional fertilizer from experts with the best results I ever had. And they say first MR 1 and then Calgreen. After the 3rd week of flowering you change from MR1 to MR2 that means 10-20-40. I personally believe now this is a clcium-magnesium problem only with those plants that get the most light. They need more magnesium. Quote Link to comment Share on other sites More sharing options...
jankahar 599 Posted February 20, 2014 Share Posted February 20, 2014 yes i find it very strange, the npk ratio seem to be way off from anything ive seen before in any other products or feeding schedules except it looks to me very much like a start up npk ratio for small plants to get roots growing fast with lots of P or just general P booster but not alone for vegetative growth or first two weeks of flowering like they saywhat stage are you in now? that mr2 flower 10-20-40 product on the other hand looks very normal ratio to be used in conjunction with the calgreen 15-0-0+cal during the bloom phase the plant has 5 or 6 stages from start to finish where it benefits from different npk ratio feeding to get optimal growth and yeild even tho they can do it with just 1 it will never be optimali would try to use both mr1 and mr2 together with calgreen thruout the grow to get different npk ratios at different phases of the grow as needed veg, transition, flower, ripening. mr2 looks more like the proper base nute for all phases and adjust with the rest of products generally speaking all the grow schedules you see manufacturers make are totally wrong with few exceptions, even tho they might work now and than you need to optimize for different kinds of strains and growth phases of plants life, the recommendations are many times simplified and put out with maximum possible dose that the grower will never need or even should use.

jankahar 599 Posted February 20, 2014 Share Posted February 20, 2014 the mixing order is always with the calcium product first or silica additive if you have, if you need to top up res with cal never pour concentrate in res with the rest of nutes in it dillute first,all major brand nutes like general hydroponics, advanced nutrients, canna etc have specific mixing order with calcium first i have never heard of this Metrop and there site seems to be very unprofessional with alot of bad english. cal&mg product first and/or micro first because the calcium bonds with phosphorous making calcium phosphate and the cal is not available to plant anymore, usually P is added last in the 3part nutrients tho if the nutrient ppm levels are not too high as you mix and you mix well before adding second product this might not happen at all but there is the risk, its basic chemistry Quote Link to comment Share on other sites More sharing options...

Metrop is one of the most professional fertilizers ever.MR1 is for growth and the 2-3rd week of flowering. Especially Calgreen is fantastic. It improves the strenght remarkable, you get very strong stems. MR1 is for the development of a giant root system and to give them a P boost for flowering.http://www.metrop.net/4a_en_soil_grow_schedule.htmlThe problem was low magnesium for those plants who got the most direct light. That was all. But next time I will use Pwder Feed Hybrid with White Widow. They need more magnesium def. metrop is very good for sativas like Kali Mist.Thanks man and thanks to Jose_ghfirefighter Quote Link to comment Share on other sites More sharing options...
jankahar 599 Posted February 21, 2014 Share Posted February 21, 2014 ''Metrop is one of the most professional fertilizers ever'' well i would expect them to type proper english if they are professional nutrient company, they have several stupid things on the site that doesnt make any kind of sense to any one who knows about plant physiologyfor example: he is referring micro nutrients as spore mixes in the site. HAHA i bet he got confused with microbes and micro nutes:D doesnt sound very professional does it, it sounds amateur they are based in north america yet they dont know anything about nutrients in englishexample2: ''From the 3rd or 4th week of the bloom, depending on the top size, give in gradually increasing doses until the end. In the last week, rinse as needed.If the soil is nutrient-rich, give this mixture 1 to 3x per week. Give daily if the soil is nutrient-poor or if you use hydroponic growth methods. Water every day as needed.'' doesnt sound very professional instruction does it? example 3: is not diluted with water: it consists only of the purest raw materials. hahahaha, its a liquid fert with no water:D yeah right, that would make it solid piece of metal:Di could keep on and on with the examples, the best example is probably there lack of knowledge about calcium bonding with phosphatesiit seems like some kid made the hole company and i cant see anything professional in anything they have on the site its all very very bad english with lots of nonsensethe creator of the product, robbie den hartog didnt even study chemistry or the plants, he studied physiotherapy at thimvanderlaani have never seen such bad website that is trying to sell nutrients with so much bad information there Quote Link to comment Share on other sites More sharing options...

The results are very good with their fertilizer. If you are such an expert, you may send your advice to the company and publish their answer here. That would be an honest way.Thank you Quote Link to comment Share on other sites More sharing options...
jankahar 599 Posted February 21, 2014 Share Posted February 21, 2014 yes, everything is ok with your grow and you dont need further advice. you seem to have the problem under control. there is not too much phosphorous.. Quote Link to comment Share on other sites More sharing options...

We would be happy if you share this knowledge to set things straight. Or shall I do it for you?And yes, the grow is fine. As I said, it is because of lack of magnesium in some plants.

jankahar 599 Posted February 21, 2014 Share Posted February 21, 2014 yes, im not going to argue about basic plant chemistry in a forum:) i will leave that alone, if you find something wrong with my initial conclusion about your npk ratio being way off and cal/mg ratio go ahead and prove me wrong i say what i see and i see the company is bs'ing you, im not the one who is selling the nutrients but i can see its far from the recommended npk for cannabis in any grow phaseyou asked help not me, if you dont like my answerits fine dont hang on it if your not going to take it i wish you all good and hope you can fix your npk and cal/mg ratio like i first suggested 10-40-20 lol Quote Link to comment Share on other sites More sharing options...

And what advice? I do not understand what you are saying.... I am growing for years with Metrop and the results are alwys fine. I forwarded the conclusions of our expert jankahar to Metrop company in Ijsselstein/ NL, since it not a US company...... Let us wait what they have to say about it and THEN draw conclusions if products are a "rip off" or producers are "amateurs" etc pp. I believe this is a grown up way to solve a question about fertilzers and nutrients instead of spreading rumors about peoples education etc. BTW: I did not forward the insults made by jankahar...... 1 Quote Link to comment Share on other sites More sharing options...
