Once plants hermie, not much you can do to stop them sadly to my understanding. I really don't know tbh, I've only had one hermie, it was genetic (Cali Connection Buddha tahoe OG), and once I saw the male parts I put it outside to finish. I sprayed it down with Dutchmaster Reverse, but i did not check for any more male parts as it was not a threat to my other plants any longer. Shame, it was a very nice looking plant, and even had some nice looking buds once it got underway, but I started it out under 6500k PLLs (compact flouros) and it was just too tight noded to withstand the amount of rain we had last fall. Bud rot that eventually ruined the whole plant.
