i went through my plants this morning, they are 4 weeks old - wearing two pairs of reading glasses and with a magnifying glass and think i did a pretty good job sorting them out. found 6 out of 20 that had very definite hairs - or to me anyway. following are photos - i circled what i think are the tell tale signs - i know most of you wont need that but it might help me and others learn.....so please let me know if i am an idiot on any of them or if any a definitely girls/whatever.....
