female and male question

Planted my seeds all 12 sprouted 3 of them are growing very fast with much fatter leaves than the others wondering if males grew quicker

males do tend to grow quicker however it is still to early to tell some seeds produce weak growing plants keep an eye on them the best way to tell is when preflowers begin to show no pistils usually means no bud good luck

I agree with AK, You will have to wait till the preflower and look for balls or little white wispy hairs usually in pairs.
