-Temperature Day/night: 20-37 / 12-16

-Humidity levels: 30-70

-Type of feeding (brand etc..): Hesi TNT Complex, Hesi Power Zyme, Hesi Super Vit, Hesi Root Complex and Biobizz Alg-A-Mic during veg. Removed Hesi Root Complex and TNT Complex, and added Hesi Bloom Complex, Akami Bloombastic and Advanced Nutrients Bud Candy during flowering.

-Watering frequency (quantity and how often): ~8l once every ~1½ week for the 3 plants.

-Last EC's used:

-PH: 6.2-6.5

-Light Power: Sun through a greenhouse.

-Type of light (LED, HPS, CFL...): Ultraviolet and infrared.

-Distance from the plant: 149597871km

I did have a problem with some green aphids some days ago which went away. But then this started to happen.

Also it doesn't appear to be affecting my Purple Kush at all. But it's abit too soon to tell.

The Big Devil XL is scheduled for harvest this evening.

Hi,

"Type of feeding (brand etc..): Hesi TNT Complex, Hesi Power Zyme, Hesi Super Vit, Hesi Root Complex and Biobizz Alg-A-Mic during veg. Removed Hesi Root Complex and TNT Complex, and added Hesi Bloom Complex, Akami Bloombastic and Advanced Nutrients Bud Candy during flowering."- maybe that's a problem- overfeeded? Maybe fungus in roots...flushing may help...no EC pen?

Keep it Simple!

Grow WEED !

The nutes have been mixed lightly.

Added ~6l of clean PH'd water to thin out the nutes already in the box. Will see how it turns out.

Might need to thin it out even more if they've been overfed.

Also harvested the Big Devil XL two days ago.

You sure it looks like overfeeding? Thought they would be more dark green rather than pale if they were overfed. Or burned tips from nute burn.

Also it doesn't look like root fungus is present since I just harvested the Big Devil XL, I had a good chance for checking for root fungus.

The smaller Purple Kush (about same age) isn't effected at all so far.

EDIT: Just realised the pictures makes the plants look abit darker than they really are.

oki. no fungus, no root rot, no overfeeding, no overwater so last to check i PH of Ur medium...if soil/compost keep it over 6.2. but below of 7.0- check your RUN OFF.

Be honest with U I don't have exp. with them nutrients above. Are u mix them all or mix singly to prevent from lockout. Try Your best. Good Luck !

Ps. Keep Growing!

hi man! well you have a looot of bottles it seems, and if the PH of your runoff is normal i would say it is probably more underfeeding than overfeeding for me. Are you sure that all your bottles goes together? and how do you mix them? sometimes you have to be careful in the way you mix some nutrients, some will just not react good together and therefore maybe make it useless. But first check you runoff PH, and maybe think about tryng to buy a EC pen, it is very cheap on evay or any growshops and is usefull when you have problems like this

Good luck man hope you solve this

Hey bro.

I used the same setup for my last grow, with Hesi Phosphorus+ instead of Bloombastic, and I didn't have any big issues. All of the Hesi products should go together, and read about alot of ppl using Bloombastic successfully with other ranges of nutrients.

And Bud Candy is just thinned down molasses and Alg-A-Mic is a plant vitality booster, both products have been used with numerous other product ranges successfully

Since this is the very end of this season I'm not going to buy the EC meter yet.

I think I'm gonna give ém a higher dosage for this last week, before flushing to see if I they hopefully can get a good end too.

I mix them all at the PH of ~6.5 and fill the reservoir of the capillary box.
