It still just looks like a plant-no indicators of sex yet...
They look pretty healthy-the one in the right side pic looks
a little funky (at least the bottom leaves do) but nothing to really be worried about-
You'd probably see pre-flowers down lower on the plant-they seldom start at the top.
One turned out to be female. I only had room for one anyways. I have to move soon so I flipped them to flower early after only 1 month of veg. So it's going to be a small yield.
