I experienced your problem myself, in that plants began flowering way early. I was told to let them grow and as season progresses they would revert back to veg. Also, if they don't revert, just harvest buds as they mature, and plant will continue to produce more buds as long as season permits. Keeping male can be a problem unless of course you want to acquire some seeds, otherwise there is very little you can do to prevent pollen from finding females. Wind will swirl and distribute pollen over as much as a square mile from site of male ( or so I have read ) , and once a female has acquired pollen to produce seeds, she has done her reproductive duty and will begin end of life cycle. In my own case, budding females showed no additional growth for about two weeks, and have now ceased bud production and reverted to veg just fine. This is interesting to me as tiny little female buds have ceased getting any bigger, while plants have begun vegging again. Interested to see what happens next. Good luck with your girls and I hope it turns out well for you.
