Help,Hints

Please if anybody has any clue about male or female plants and can I tell befor going in to flowering?All comments welcome ,hiw do you think my plants are doing week 5

females will start growing little white hairs around the corners of the branches and along the flowering line! males will start growing round sacks around them they look like little balls! i just started with hydro growin my plants are only an inch but they look healthy yours are looking pretty good also! if you got room id grow them a little longer before id bud them!
