I just had two hermie on me that I believe was from cutting the fan leaves off right after flipping to 12/12. I've never cut fan leaves before, always left them on. This particular grow I needed to because my tent was getting too crowded. I feel it stressed them out and I read somewhere that if she feels she is in danger she will focus on seed production so life can continue. Or something along those lines lol. Maybe they hermied for different reasons but my environment was dialed in, I can only suspect it was from cutting the fan leaves.
I would recommend you give her at least a week to recover!
