Magnesium def?

Growing several diff. kinds of cannabis (top dawg, blue cheese, super silver haze, arjan's strawberry haze, LSD, mazar afghan skywalker and lemon g) all are growing beautifully except super silver haze. the leaf edges are curling up and drooping down.

I have a couple plants doing this an all others nice healthy i also would like to know what this is cuz i've been feeding every 3 days with just ph water at 6.5 since birth and they look like this about 5 6 weeks

Hmm, maybe its a lockout? I dont know why youd have a def with one but not the others.

Id say just flush it out and work your the nutes back in slowly. Some plants can tolerate more nutes than others and v v


I also have an SSH growing and it looks fantastic so far, and I usually feed at 1/2 strength.


What nutes are you using and how much?

i am guessing it is heat stress. i had a plant with 6 cfl under some foil and had that prob

Hes prob right, I looked again and the leaves look healthy just the upturn...Temps?

Same with my plant bro started due to low humidity and high temps. Wouldn't stress or worry over it though

i havent been using any vegging nutes but i just started flowering and im about to start using big bloom and tiger bloom by fox farm. the temp was pretty warm in the room so i put another fan that blows directly up and brings in fresh cool air. the temp dropped alot, should i treat for mag def or do u think its all from the high temp? ur help is greatly appreciated guys
