Hey guys, I have some plants that were put under a 12/12 light scheme a week ago and it seems like some of them are showing their masculinity 
I think these guys are male, but if anybody could help me be more positive about it, that would be awesome.
Plant 1:
Plant 2:
Also, if they are male, how long would you say I have until I risk them pollinating my girls?
Thanks much.
