Im having trouble with some black berry kush. I am running 32 plants off two 1,000 watt lights. I have my clones in a soil/ready grow mix planted in coco pots. I water once a day with a flood and drain technique. My problem is the leafs are yellowing from the inside to the tips on all new growth. I'm thinking a sulfur deficiency, but from what I know soils are abundant with sulfur. In case that is the issue I have top fed the past two days with epsom salt water. I really don't know if thats the issue. Feedback is appreciated.

I was feeding it Pure Blend Pro-Grow during the 7 day veg. I just switched to Pure Blend Pro-Bloom. The highest the ph got was 6.4 or 6.5. The temp stays between 60 and 79. I don't know exactly whats in the soil I'm using. Happy Frog Soil and Ready Gro.

i would use a seekelp any thing with magnessium and nitrogen and spay them down with it, botanencair makes a good product for it. and flush them out
just incase there lock up. the seekelp is a organic and its a very low mag/nitrogen content, safe foe leaves and such

So the ph reading you were just talking about is for the water or the soil ? have you tested some run off or used a soil ph meter ?

yeah sea kelp doesnt really help with sulfer its not a cure all ...
your right about it not helping with a sulfer problem, but im not sold on it being a sulfer problem, Im
thinking its a nitrogen def due to his change from a grow nutes to a bloom, bloom having less nitrogen
than the grow having more N value.

Im no pro, but from my little experience with botanicare it takes more than just pure blend gro. Correct if Im wrong, but if the clones are new and if taken correctly. Shouldn't the clones have a nitrogen deffeceny.

This is no nitrogen def, it is starting on new growth, n def starts on old growth since it is mobile. This is a Fe (iron), most likely due to ph being off. The fastest way to get some Iron in them is by foliar feeding in combination with getting the ph right and supplementing their regular nutes. Got rusty water?! You have grown in your grow space successfully before, have you?! Just to rule out outgassing.

What should I be foliar feeding these girls? The ph is set to 6.1 My water is not rusty. No, I have not grown in this grow space successfully. Whats outgassing?

I tore the tent down, threw it out, lined the floor with plastic, lined the walls with mylar, and hung the lights from the ceiling. Ill keep you dirty dogs informed to see if this is, in fact, OUTGASSING.

Looks like light-bleaching to me...

Did you go straight from a low/moderate cloning light and put them directly under the 1000 watter???

That'll bleach them out for sure, ease them into the strong lights.

It's not light bleaching, look at the picture again, one of the faded leaves is in the lower foliage. If it was bleaching it would have affected the top growth more uniformly, it wouldnt have randomly popped up on new growth that low on the plant and leave the other foliage normal
