How long to determine sex?

[JohnnyBlaze]

How long do you have to wait to determine the sex of the plant? The reason I ask is that I don't want to wait on a plant until it is too late. Here are three plants that are about two months old. I think the first one is a female but can't tell about #2 or #3. #1 has about a two week head start on the others.
All of the plants were grown from seeds in generic planting soil. Plant #1 is 24", Plant #2 is 18", and Plant #3 is 12".
Thanks.

It's hard to tell with those pics for sure man. Have you thought about using clones from them to sex them?

You haven't told us anything hardly about your grow.

If you would tell us the answers to the appropriate questions in this list, it would help us help you.
