When do Seeds form? Hermaphrodite plants

Hello all,
My girls are in flush right now. I have a really great looking crop of Chem Dog's and a small, less attractive looking crop of Dutch Dragons.

I just noticed the Dutch Dragons have seeds popping off the tops. I'm guessing they are hermaphrodite genetics b/c they were grown from "feminized seed" from a dutch seed co. It's my first time growing either of these strains.

Basically I'm wondering about potential pollination of my other plants. I haven't noticed any seed pods formed on the Chem Dogs and they're almost finished w/ about a week or two left to go.

Does anyone know typically when seeds form during the cycle. I figure at this point, if they can't be seen, then there's not much of a chance of having a hermie batch of Chem Dogs.
What do you think?

I already cut down 5 P.O.G. plants which are 8 weekers and no signs of seeds there.

I have the same problem ive researched and asked around you should be fine,the seeds should be mostly fems off a hermy but grow em out and find a killer mom if you not sure flower a month then revert your choice back,it took two months for mine to go back,let the seeds develop dont be impatient,good luck my friend
