I am thinking most are showing as female!! Check these pictures below as they are the best shots I could get... the rest of the plants have the same looking growth.
Tried to take some better shots but this camera sucks. So these things are what you are talking about watching out for? This is another pic of that plant:
those are "pre-flowers" they could be either or. i'm still saying male on this one. you probably won't see new ones until you are on 12/12 light schedule. i normally see "hairs" on females before i see the actual pod. on males i see the pod but no hair.
I would not confirm sex by any of them yet. the one that got the hair pointed out, probobly, make sure its actually a white hair from the plant, and you probobly got a fem. from here it looks like an ambient cat hair or something.
Im not sure but when I asked a question about those type of points coming out, someone told me that those were just new growth sites
Im not sure though, I have mine on 24 right now and I have been seeing those "shoots" the whole time and I also am getting some of those things you circled too
