Update
I kept an eye on the hermie and it put out more male stamen so it's gone. The other four plants of that strain (Z11 sativa x NH) all show calyx forming into seed! There were no male stamen that opened so I don't know how this is happening. I was tempted to shit can all these plants but I decided to wait and see how things look in another couple of weeks. If I need the space I'll cull them out.
