#1 #2 #3 #4 #1 is one plant #2 is one plant #3 & 4 is one plant so just 3 plants in all. I think #1 is male (may need to zoom in), and the rest are female, but i'd rather check and be safe than sorry
I'm 95% sure, that other 5% of unsure is because I've only grown females, but it looks like a dude to me.
#1 looks like a definate male to me, no harm in waiting a day or so though just to let those pollen sacks swell up a tad more.
