Male or Female?!

k my plants are doin pretty great right now.....they arent big enough to start sexin em yet but when the time comes I wanna know how to do it!
and when would be the best time to do this?!
any tips?!

most plants will start to show at the bases of the branches after around 6 weeks, you will always see to small green spurs where each branch comes out. Ignore those and look for a small bud growing right behind the spurs, a male will look like a ball with a hook, a femle preflower is longer and spur shaped, you may or may not see two small white hairs coming out of the female preflower.
