its a girl!!

checked my outdoor grow the other day and all but one look to be females, my question is should i be able to tell this early? i thought i wouldn't be able to tell until they started flowering and with the summer soltice being just a day before i checked they shouldn't be flowering yet, any thoughts?

might be pre-flowers........how big/old are the plants

they are all a little over a foot tall and i started them in doors back in march or april can't remember,

and now they are outside???my best guess is preflowers.....pull the males

yea they have been outside for a while now yeah i'm gonna pull the males +rep
