Hey PF thanks for stopping by, your right thats not the best description.
The internodal spacing on the dud'd area is shorter than the rest of the plant, of course it will help to have prior knowledge of the strain.
See the right side of the branch with its two "longer" healthier looking growths. That is what the internodal spacing on rest of my gg4 looks like
Look at the left side of the branch.
Does that look like gg4 to you?
Healthy gg4 below. I treated these plants and gave them a heat treatment, after the heat treatment is when the "dudding" appeared. Only on some of the branches on some of the plants.
I was about to take a bunch of clones and monocrop the next round, but I think I will see how this one plays first.
