This strain has been giving me problems for a couple years when I light dep so all the tops are fluff only the bottem of the top branches have nice full buds
Go through my thread. Are the buds still filling out & growing? If the answer is yes you let her go. If they've stopped, and along with that no new pistils are coming out (again related to bud stacking) then I wouldn't wait too long on the trichomes. Sometimes they just don't turn.
That was an incomplete survey, of course, just a couple of examples of what will influence whether or not you chop.
