I think I see some sort of primordia at the upper nodes.
Just one spot on each plant.
Left pic, 2nd node down on the right.
Right pic, 2nd node down on the left.

Very small, and so very hard to tell, especially from a photo, so I won't swear to this, but they look female.
Males can fool you sometimes, though, so I'd wait for a flower with a pistal (white hair sticking out and up) to show up.

Watch those two places and see what happens, they might mature enough to tell for sure in a few days or they might remain primordial.
Keep close watch on the other nodes as well.
