I am positive they are pistils, they are white ant there are lots of em. In fact I'm pretty sure the plants are all female, I'm just nervous about hermies. This is my 2nd grow (first in about 6 years!) and the first one went to seed from a hermie that was almost surely caused by stress. I have been much more careful this time and learned a lot more (thanks to this site) so I am avoiding stressing the plants. I just freaked a bit when I saw what I thought looked like a male calyx. Thank you all.
