Are these female preflowers??

The picture isnt very clear but you are looking for a white hair that is very fine and thin - a male will literally look like it is growing balls all over it when it starts producing pollen sacs and a female will kinda look like it is growing a white tiny root out of the calyxes.

Looks to me like it is female. Out of the Calyx you should see the white hair. But for as clear as the picture shows on my phone, it looks like a she to me. If you have a little ball growth at the bottom of the shoot near the node then you have yourself a male. Hope that helps.
