male, watch to see if there are any little white hairs or calyxes. with the males they look the same at first because the leaves in the male parts look like white hairs. if you get the round pollen sacks hanging down after a couple weeks its ready to release pollen . there will never be white hairs on males or hanging pollen sacks on a female. A female in 2-3 wks flowering should have nitoceable white hairs and preflowers even Sativa types
