congrats man... you got a preflower quick.. sign of a healthy plant.
but in pics 3,4, and five, i see males... pick one is female for sure, and pic 2 i cant tell...
picture 3, 4, and 5 are males. Picture one looks like its a female if thats a white hair the picture isnt very clear, and picture 2 doesnt have any sign of sex yet.
I agree that the first looks female but some of the latter seem to look like they have balls so careful and get them out of the room, maybe you wanna keep them for seeds but get them way outta the way. Spray them down with some water to prevent any pollination potential.
