There's a good and a bad side to this scenario. Well, bad and worse. The bad is yes it hermied on you and you can keep tweezing those nanners off, but you have to be very tenacious about it as they seem to pop up continuously and it's nearly impossible to find them all each day. I've done this for weeks at a time, every day going in with tweezers and inspecting and yanking the pollen sacks off. Pain in the ass it is. As far as watering to neutralize the pollen, not sure if it works unless the sacks actually open and attempting to disburse the pollen. Those sacks, nanners, are mother nature's way of protecting that pollen until they open up. I've always tweezed mine, never tried spraying the plants. The bad part of leaving them and trying the spray deal is, when you go to smoke your harvest, any pods you didn't tweeze off will give a nasty, and somewhat harsh taste when it burns. I hate the thought of ripping out a plant late in flower because of the nanners, so I try to REALLY stay on top of the plucking, as opposed to leaving them on and spraying with water. Better to invest a bit more time and effort every day, than to deal with the nasty taste of all that pollen after you harvest. The choice is yours, either way it sucks, but not as bad as ditching a nice plant late in flowering and close to harvest. Sorry about your luck here, hermies suck.
