Could this curling be from too much exposure to oscillating fan too early?
Also bugs me that all 4 of these started at the same time (although 2 different strains) show no uniformity. Think the smaller ones will bounce back?
This is my first go at autos and know they may be a bit more sensitive than I'm used to. This also came about the first time I gave them nutes but they were such low numbers and didn't look like nute problems to me.

-Strain in question grape walker kush (mephisto genetic) (two on left side)
-other strain gorilla og (short stuff) (on right)
-all straight into pots 9/11
-last water began light feeding of advanced nutrients sense grow a/b 1 ml/l, cal mag as needed or .5 ml/l, mammoth p .3 ml/l
-3x3 tent 315 watt cmh 20/4
-80-84 degrees
 
This was my first post. Did I not attach file correctly?

Sorry, foguring out how stuff works. Bottom pic is turned. Grape walker kush on left, gorilla og on the right.
 
A fan could definitely curl leaves but this looks more like high heat or low humidity to me. Do you know the RH? I'm not familiar with cmh enough to know optimal temps but if I were to guess, 84° is a bit high.

Are the the both curling, Mephisto grape? If so, they naturally look similar to that. I believe it's from the grape "crinkle".
 
:toke:-- what's the distance to the lights from tops? And yes, the RH% too,... any combo of high heat, low RH%, strong air movement, strong light intensity can cause the edge rolling,... that CMH is a powerful light! Yeatster has a point with the Grape, it might be that leaf distirtion, but as a cross, I think it unlikely,......what are you growing in, soil, brand? How rich it is makes a big difference in how they start,... if it's mild, the feeds are late in starting,... The one big plant is a mystery to me, when 3 others are about the same, and undersized,...
 
Sorry was under the weather for a bit. Thanks for all the suggestions.
I think it was a bunch of factors. Everything seems much better now. It's my first try with cmh as well. Think main factors were low RH, along with a little too hot. I never considered the crinkle lineage (duh!). The plants I had most problem with were the crinkle, but think with everything, especially considering my rh seems better and things will cool off a bit. Than i should be good till next thing that looks odd to me.
 
Looking better, they need to be a little bit cooler still. Slightly droopy leaves but I've seen the on other gorilla og autos before. I backed the light off some and might even put some on buckets to make an even canopy once temps are more reasoonable.
