Good question. Start plucking the balls off. Try to figure out why it went hermie and then try to correct it.
If ya got other plants just kill it and work with the others.
Yea hermies suck man. I've got one now and he's making probly 1/2 the buds as the females I have (guess that makes sense since he's only half female). But yea if it's your only plant just pluck off the balls and learn from any mistakes you made that might have made it go hermie.
^^^yea it's my only plant right now, and my first, so i'm just learing from my mistakes. My plant overheated once when my fan died, and it has had some serious light pollution. Also, will plucking the balls off make my plant produce more?
