Seeds in a spring grown autoflower

I recently completed a successful autoflower crop, but had a weird yet interesting finding. In the last couple weeks waiting on trichomes to mature, I notice after a couple days of rain that I had seeds in bud and they were actually germinating on the plant. Never seen this happen. I planted a couple of the germinating seeds and they seem to be doing fine. Anyone else ever seen this? What type of plant would you expect to get from an autoflower plant seed. No male plants.

On a second grow I started later with regular sativa stain seeds, I was surprised to see male plants go into full bloom in mid June?? Usually wouldn’t expect flowers until August or later?? This happened with Thai stick plants, but not with durban poison planted at same time.

A tree in the way perhaps?
