Lets talk about sex baby

Ok so i have 8 plants that have been on 12/12 light cycle for 10 days now

3 of them i am positive are females because the pistils are pretty obvious, but the other 5 just look like balls.

Any chance that those(that look to be male) might be female and just there pistils havent come up yet? I am growing bag seeds, and there about 2 1/2 months old.

Thanks alot:rastabanna:

ditch the balls!

Ended up being 4 female and 4 males, the males are gone now.

Il post some pics soon.
