My favorite suspect is the anti-scald valve getting munged up
with crud.

Shut off the water to that branch, dip the shower-head
in a gallon of cheap vinigar, and then open the waste-cock
on that hot-water shutoff, to suck the vinegar backwards
through the valve. Let it sit overnight, and then blow it
clear and see if that helps.
