looks like its stem rot but its farther up the plant then usually seen , i have one right now with stem rot cause of the rain we got 2 weeks ago was crazy such heavy down pours , but i use rose dust its a fungicide and insecticide , kills slugs , leaf cutters and many other MJ draining, stressing bugs and i will give the base of the plant a lil puff of the rose dust so if the weather changes to wet and humid i dont get stem rot 99.9 pecent of the time , but theres alot of things to use for your plant like a fungicide to stop the rotting try your local walmart or garden store
dackman Reviewed by dackman on . Brown ring around branch Hey, I've ran into this weird spot in a branch today. Theres a brown ring that indents slightly around a branch in the middle of the plant. I dont know how I would get stem rot that high up on the plant? Normally its near the base. The plant is healthy otherwise im just worried im gunna loose one of the two colas :(. I know i didn't crop the pic right, but click on it and zoom in to see it. Rating: 5
