Once you go to flower the sex will start to show. Unless, you have light leaks and stress the plant, then you'll post--what wrong with this? There are excellent archives here to show you what to do next. You might want to start digging around. I always come back here to look for information in the archives. Utilize that and the excellent master growers on the site (not me).

There are some really good threads here on sexing your plants! Like a kid on Christmas morning! You'll be addicted to growing before you know! Good luck with it.:rasta: pr
