Please Help (Sexing Plants - Pics)

This is my first time growing from seed and I'm having problems sexing the plants. Can anyone tell if these are male of female from the pictures I've attached?

Note: My digital camera is not working so I had to take these from my iPhone. Also, I tried to raise the levels a bit for more detail so the color may not look right. If these pictures are not good enough I'll try to post better ones tomorrow.

Thanks all!!

Sorry, I can't see a thing. How long since you put them on 12-12? Have a magnifying glass? Your females should be real obvious white whio antennas lol sticking up. Yer guys are more ballsy looking lumps. Good Luck.

dude u gotta get sum closer shots real tight in between the leaf branch and the nodes!!!important on top of the node,, right on top, off to the side a little will be a small single protrusion and if its more than one its a ball slang'n dude if only one then fuck her good so she stick around!!!!

are you even flowering yet?? Definately not close enough.

Sorry guys, I have a shitty camera phone and I still can't get mt digital to work!!
I think I have all females. I'll try to get some better pictures posted.

Thanks
