I started flowering on may 10th. for veg plants were in those biodegratable pots. when they were sexed i moved females into 3-4 gal pots. about 10days after flowering. i think i have about a month left to go. i know this is a slow grow type. i water around 2x a week. once w nutes once w molasses. there was some stretch when i first flipped to 12/12 but that seems to have slowed.
I have two major concerns- 1) the clawing on the top leaves, claw, twisting n thinning.
2) the lack of trikes on the smaller fan leaves. When i open the closet door after the rest period there seems to be less trikes then when i closed it that morning. then after light has been on and door open for a bit...they seem to reappear. is that normal?

Also as this is my first post, im sure i broke some etiquette, sorry for that. Thanks for the help.
