Sex my baby up. Please. (Pics)

Okay, maybe I wasn't completely clear and I apologize. I purchased 10 feminized seeds of Brainstorm Strand. currently I have 3 plants, 1 that is of the brainstorm strand that I know is a female because it has hairs already showing. Along with the purchase came 5 free seeds of Skunk strand. The plants that I am trying to determine the sex of are of the skunk strand which were not all female seeds. So, I ask again, can anybody determine by the pictures I posted if these plants are male or female? I changed my light cycle to 12/12 THREE weeks ago and it will be 4 weeks on Wednesday July 23rd. Please help me.

dunno thats wierd that they havent already showed sex!!!

you could keep it till it pollenates and then stick the pollen in a bag in the freezer for when you want to get seeds from a female you can just brush the pollen onto a certain nug and get seeds that way. but alone the males aint good for shit but rope
