The pics below were taken about 10min ago. I haven't checked the grow for about 36hrs and I walked in to find what you see below. The leaves are only doing it for about the upper 25% of the plants and there are other plants in the same tubs and on the same rez water that are doing just fine. Could this be a genetic thing?? I am totally confused on this, the third pic is of a plant that is in the same tub as the plant in the second pic. Please someone give me some ideas on where to go with this. Also i should note that the bud production on those plants have more or less stopped with a less than impressive production.:fire:

Here is some info to help you with your opinion. It is a true aero setup, using GH nutes with AN bloomalicious, cal-mag, hygrozyme, and c2o2 of 17.5%. the pumps are set for 4off and 1on.

if all your levels of ppm and ph are at what they should be and this is only happening to some plants but not others...

i would check your roots, check your drippers make sure they are all sprayin even amounts.
if its a flood system you might want to check the medium and make sure the root structure is normal.

The roots are a light brown, almost cream color. I checked every sprayer and they are all functioning. PPM is at 1125 +- 75 on any given day. these plants are in there 10th week of flower. What about possible light stress?? Should I drop the light from 12/12 to 10/14??

whats your medium? if its dirt it maybe a bug eating your roots. if its hydroponic could be same thing but may also be an extreme salt buildup on roots. may also be temps as someone said, but i think its your roots. good luck. also if ph is correct, it prevents nute lockout. hopefully its an easy fix good luck

Probably already looked and realized it wasn't this but you sure the lights not just to close to the tops? That would explain why only the tops are effected.
