Help determining sex

Been growing 13 Supergirls for almost 2 mos. Already chopped out 6 males. I cannot tell if this is a female or a male. There are little sprouts coming out at the nodes. They are sorta-kinda ballish looking but have flowers coming out. Are these balls that have sprouted? Or do they indicate female traits?

Help please...

these look like flowers but get a 30x microscope from radio shack to tell for sure
