Its been a week since we've gone 12/12 and everything looks amazing.
Made a few modifications to the scrog screen tonight but wont show those until tomorrow. They are stretching a lot now so I had to run a couple of lines to tie down some tops. Now the temps are about to drop i can get the lights closer and roll the fan up to 100% and still keep temps in the low 70's, Sweet!
Looks to me like there is some sort of leaf deformation. Those "hairs" to me look like they follow the path of the central leaf vein and then extend beyond. Almost as if the tips of the leaves didnt finish forming. They look good and healthy though and if its not bothersome then who cares.
