A black patch appears on stem, kills entire branch near it

I listen to the CBC gardening show in Canada with Edward Lawrence, but they don't seem to take questions related to cannabis growing. Last year some friends and I saw some strange sort of 'localized rot' in some of our plants; a black spot would appear in the stem, and spread to a branch, and that entire branch would just wilt and die. The rest of the plant would be fine. What's going on with this? It's only occurred outdoors.
