Is this a hermie or a calyx? please help

after looking at the hairs closer....if those are the first preflower hairs you had...they will do that...thats what the hairs do after a while...but they get replaced with new thicker white hairs...i really wouldnt worry just yet

Just remove all the male bits off the plants and you'll be straight.

yeah you dont have to start worrying about the pollen spreading until you see the green balls turn white and start to actually open up. so if u wait and check if you still have any plants left you will have a better idea of what your dealing with later down the line.
