i grew grape pupil by massmedical strains and it was the most resilient plant i grew and i grow outdoor mid michigan so usually high humidity's no bud rot or powder mildew on any of the 3 plants i grew and they had some decent size nugs
this pic is from a couple years ago. I made a incision above the hole and pealed it back a bit so i could find what made it and it was a fat ass worm borer about as long as my pinky
this year i got rid of all the grass in my garden and put mulch down and I noticed a huge decrease in leaf hoppers and only one or two branches on one plant has gotten the phytoplasma. usually all my plants get it around the whole plant. I really think it is leafhoppers that cause this
