My plants are about 2 1/2 weeks into budding and I noticed branches starting to die on some of the plants, I got a closer look and seen stem cankers forming. They are located about 10 inches down from the main bud mass and the infected area is about 1-2 inches in length and is making the stem die. The infected areas of the stem get brittle and the whole branch slowly wilts away. Is there a way that I can cure this, prevent it from attacking more plants or should I just cut my loses and clip the whole branch to prevent spread.
