Appear to still be a couple of weeks from harvest, depending on strain. Mostly white pistils, very few brown. Highly recommend getting a 40x to 60x jewerly loupe or handheld microscope to check trichomes. That is the gold standard for harvest. I haven't experienced hermi personally so I don't have any advice on that. I have read that stress will cause bananas and to cut them off immediately but will defer to others with more experience. The last few weeks of flower will test your patience as not a lot of visible change is going on with plants. Buds will fatten up some but mostly waiting for trichomes to turn from clear to cloudy/amber, depending on what type of buzz you are looking for. Good luck, buds are looking beautiful!
