The lights are off now, but I will check on them in the morning when the lights are back on. I never noticed any male flowers at all and then BAM! All of a sudden it seems like every single plant has a few seeds in the main colas.
You have hermies. Sorry man. The male flowers can be incredibly hard to spot, sometimes single male flowers will grow under 100% female looking buds. (happened to my last crop) I didnt notice till it was too late. Sounds like your in the same situation. Check the plants, lift buds, look between buds, but mostly right underneath the bud. They will have popped now, they are only like the size of your pinky fingernail, maybe smaller so they can be hard to spot.
Sorry bro, I know how you feel right now. It just happened to my last crop, They all got seeded, had to get some new genetics.
Personally I hate feminized seeds, I wouldnt buy them and if I did I would only buy off of a reputable breeder, even then theres no guarantees you wont pop a hermie now and then. I would rather pull males then deal with a plant that might have a rececive hermie gene. Once you get a good female just clone that bitch.
