Your plants most likely are going to grow seeds now. If you look at the buds, you can see where the pollen touched. The calyx will begin to swell more then the rest and the hair will be dead on that calyx.
Make sure no more open or you will end up with all seeds.
Take one that you cut off and take it outside. Squeeze it between your fingers. If it coontains a yellow grainy substance your going to get seeds.
