Agreed, I'd look for some kind of borer. I had something similar, but it was my fault, I was doing some LST and when the plant was small I tied it down, but I made the knot too tight, so as the plant grew the string cut into the branch and strangled the branch.Something is likely eating that branch, it's no longer getting water that it should be. Either a caterpillar ate a hole in the branch, or there is a mold problem in the roots and possibly that stem. Go to the base of the dying branch and look for issues there.
Has the problem gotten worse or has it gone away? Do you have a newer photo?not sure whats happening...my plants are just wilting in certain spots,not the whole plant, just some branches and now the top???? wtf??
