All three plants are hermaphrodites, however, plants 1 and 2 are showing minimal signs of male with seeds developing only on lower nodes, while plant 3 looks mostly male with a few pistils only on the very top nodes. I've decided to pluck the seeds from plants 1 & 2 as they develop, and to toss plant 3 to make room for the other 2. It's not ideal and I plan to buy feminized seeds or clones for my next grow, but the bud I got the seeds from was actually really good so I'm going to try to take 1 and 2 to harvest.
