i have quite a few plants going right now. 4 are 2weeks and a day old from seed. 2 of them are getting really bushy with leaves, the other 2 aren't so much, but the latter are really starting to have that thc/bud smell. does this have anything to do with their sex? i'm thinking that the 2 that are starting to smell are female, but i'm inexperienced so i could be way off here. theres no way i'm pulling any plants on a hunch.
