russrahlanswered grow question 4 years ago Ohh no!!! That’s bud rot! I’ve had that happen once before on very large colas. It sucks. You can try and cut out the bad parts but really it is a health risk to smoke. I ended up making oil with the bad shot and having to push the final ISO rinse through a 0.2 micron filter, which was very dam hard to do. Lol
