Just went through that M or F sweat myself. First grow, too. Each of my 3 plants "revealed" at different times, but within a few days of each other.
I was concerned I didn't have enough magnification to be able to tell. But when each one started showing, there was no problem distinguishing which way they were going.
Ended up chopping two males. My one remaining girl is enjoying all the new attention - and light - she's now getting.
By looking at your pix, its obvious you have enough magnification. The white hairs will be pretty obvious (as will those unsightly round balls) and you're looking in the right places on your plants.
Be patient friend, you'll know soon.
