Thanks for the Rep!Another solid point the cases i’ve seen are more like live resin drops oozing out of the buds but maybe this is the start of something good LOL. Thanks @NAGreengo!
After seeing your second photo post, I may reconsider my last thought and diverge back to my first. That could be Spidermite or Russet Mite web, with resin secretions traveling down them. In this case, I would give them a good foliar spray soak a day or two before harvest to try an wash as many of the Mites away as possible. Followed by 48 hours of darkness in a cool space. It is hard to tell though, especially without spotting the critters.
