Help Identifying Preflowers. Guru Challenge!

alright guys. these just showed up today and yesterday. the females are pretty obvious because they have little hairs coming out of the preflowers. but I can't tell if some of these are female flowers that hairs havent come out of yet or if they are males. so what do you guys think?
pic 1 ais def female.
others? thanks riu!

Far left pic is def female, need to wait a little longer on the other ones, those aren't pistils and could just be new growth.

hehehe... i love this... 1-f 2-f 3-m 4-f
