Seeing this brown discoloration throughout the entire tree of a Coast Redwoodz

And this ashy discoloration is localizes to a single branch.

Any ideas what could be causing this?

It’s been in the 40s a few nights there, reaction to cold?

Curious as well. 40s shouldn’t bother a coastal redwood like this unless the tree was already compromised.
