not helpful.. if a plant hermies with minimal stress, i hope, then it's a bad trait to pass on.
Bubble hash is an option, because it doesn't apply heat nor pressure to the plant material. relies on ice cold water knocking trichomes off surface of plant material -- the least amount of damage donen to the plant material, the better the quality of hash. (i.e. don't use jagged ice, don't stir too hard that it breaks it down too much.. etc etc... the melt should be mostly melted by the time you stir. add more each cycle to keep it ice cold.)
This is an option if oyu can isolate teh plant. some nanners are importent, but those look pretty substantial... i'd err on safe side if the nanners are all over or sacs are forming... if you cannot isolate, toss it... if only a few nanners, can try plucking them each day.
