I had an issue with bud rot several times in one grow. First branch was removed on week 6 of flowering and I thought the rest is sick as well. But she was pretty strong. Two weeks later there was another small contamination in the central bud and one side side branch. I’m really surprised it didn’t kill her entirely, threw out a small amount equivalent of 10 g of dry buds.
The bud structure was not satisfying. Probably due to the lack of light in the beginning of flowering and nitrogen overfeeding. Most flowers were not fat enough and a lot of leaves occupied space between them.
