Has this rotted?

[MsLinda]

This is my LSD plant which is ready to be harvested any time now. 2 of the branches look like this but the rest of the plant is ok.

Should I cut this off and toss it?

I'm not certain but that looks similar to light stress. Cupping of the leaves and bleaching of flowers. What did you figure out?
