I see what you are saying about the one opening up with pistils....I'm thinking it's trying to produce a seed. Only time they've ever developed on me I totally missed seeing them. So not 100% sure on what it looks like when they start to develop a seed but it looks like how my buddies just looked sort of when his went herm.
I'd say, it happens...most new growers would chuck it out of fear but plucking should be cool some plants chill out after that....if you cloned her that herm trait would likely disappear, so that part makes me sad i killed my ice and face on fire female/herms....cloning them and trying again may have been the best route.
I gotta say, good eye...good scouring of your plant...your ladies have a dedicated papa
