you gots a long way to go kiddo. I started to flower at 5 weeks and that can be considered early for some. most people wait until their plants have 9-11 leafs on each node, which i also had. also, mine were about a foot tall when i started to flower.
Also, the plants dont start to show their sex until a week or so into flowering. males show it first and once they do, kill (or just separate them and make hash from the leavs!)those suckers for some good sensi.
Read the growFAQ like its your job and you'll learn alot.
Happy growing!
