Need help with male/female problem

I'm only 4 days into flowering and I have about 4 plants that look like they could be males so far. If they are, how long do i have before i have to remove them? I'll update this with the other plants as they start to show. Have 13 total.

y would u wait?

Judging by the pics in the first one not too long. From my limited experience you have 1-2 weeks after you start seeing them until they open.

No reason to wait - do the deed.

just took out/down 6 of my 13 plants. Hopefully i judged correctly that they were males. I think one was a Hermie but i got rid of it just in-case. thanks for the help.
