first pic is a male
the other pics dont appear to be showing any sex
for females, your looking for 2 white hairs
how many plants do you have?
males tend to show sex before females to keep your fingers crossed.
keep an eye out for those white hairs, you see anymore balls like the first pic up there..kill them
They were originally under thiscool man...good luck
what lighting were you vegging with? and what are they under now?
with flouro tubes the light is most intense at the middle of the tube..also the light intensity dramatically decreases the further away from the bulbs..just something to think about.
you would normally want to keep the plants small or LST for better light penetration to avoid getting the little popcorn buds that arent getting adequate light.
With fluorescents my plants TOUCH the bulbs. But mines are 40w T12s I can't image you'd need more than 4-6" (probably closer) and a fan on the bulbs keeps them quite cool. I predict the 3rd and 4th are girls, 75/25 F/M on the 2nd one. hope it's all girls!
I have mine outside the cabinet right now. After I sex and have more room I'll move it inside the cabinet.I'm looking forward to pics, btw I covered the blue light up with black electrical tape, forgot to mention that before. It should only take a few minutes to see a difference in the smell.
