So this one bud only has some grey looking spots I'm in the flushing stage 9 days left until harvest. Ffof, 600w led, 68-78 temp, pH 6.8ish, Rh 40%,constant air flow want to make sure it's not something that will spread or should i harvest

Yeah I don't think it's mold either it maybe a from being touched I had a friend jamming my microscope around two days ago the other grey spot is almost exactly opposite this one like someone squeezed it. Just wanted some input from the experts
