Hermies.....almost harvest

2-3 weeks from harvest and male flowers are starting to appear on almost all my plants buds. I started out with 10 plants and 6 of those were female. I killed one plant uesterday because the flowers were becoming closer to maturation. Is there any way to detour this or mshould i just go ahead and harvest early?? Also, what could be the cause of these plants hermaphroditing (sp?) so close to harvest..Anyhelp is greatly appreciated, and thanks ahead.

you could try to just pick off as many of the sacks as you can, I got a garden full of hermie's right now, i spend a lil time every day looking for new sacks to try and keep the pollination to a minimum. i have no idea what would cause it this late, some sort of stress obviously. but if you don't want to take the time to pick them off you could harvest early, but i harvested my last plant early and it didn't turn out very well, but that was my very first plant ever, so for me, just getting it all the way to the end was satisfying.

stress is normaly the cause of hermies or heat stress nutes to high of acidic soil level or there just a retart strain well dont think to higvh of nutes would do it otherthan it stress em when opver ferted
