Yes white hairs are pistils, I know everyone sez white hairs, white hairs, but when you see them you will know!

Don't worry about the males. They have balls. You can go quite a while before the balls mature and spread pollen. You will know when you see them and cut them down (pang) well before it's time.

I have found the biggest plants ususally always turn out to be male. If you have a hermie kill her too, everyone always wants to try and pick off all the balls, but it never works. LOL

Plants look good, but with all that yellow light hard to tell. I'll check in later when pics are up!
