do you have any pictures of seedlings that are male and female? can you tell a difference? these seem to look like males. post a picture showing the difference in seedlings stage if you will.
Can't say that I really have any accurately depicting male vs. female, I usually just take group shots until they sex and then I usually just chuck the males.
I find males usually have bigger and thicker stocks, are darker in color, have thicker more papery leaves, grow taller faster, have a kind of pungent smell to them when rubbing the stalk, and if you look closely the little 'spikes' or whatever they are at each node are different (2 on each side of the main stalk, they're there way before preflowers).
Yeah, they usually do look and smell different, and I guess if I had a lot of seeds and space and numbers I could just go off of instinct. But I've suspected a plant to be male and been proven wrong on several occasions in the past, so I wouldn't really recommend winging it.
Just let em keep going for another 2-3 weeks and you'll know for sure anyway.
