your plants look great, I ran the feminized promotion version and had a huge hermi fest, but I heard they changed the parents in the "release" version and have only heard great things about that, never seen anyone grow the reg version but I hope you find some great mothers :)
It looks a bit like maleflowers starting to form in your last picture, but I would give a few more days before deciding its fate, I have seen plants look like that before and then a few days laters white hairs are starting to pop out
