I had same issue ending week 5 flower. but i didnt catch it as fast as you and pollen sacs were open and dropping pollen. only on lower branches. i picked them off and havent seen any more, no nanners. and no seeds as of yet. my other 2 plants look fine and no signs of hermie or seeds so i am praying they will be ok, with very minimal seeds if any. im finishing it off as so close to harvest. but if i found it when you have and sacs werent open, id definitely remove it from the tent, easier to kill it when its not already packing on huge buds :(
I had some nitrogen issues and i topped and lst'd the hermie which i think may have been a possible reason in the hermie. yours however looks extremely healthy so what a bummer. hope you get a good result man
