I am having same problem as DTouchberry! I just posted pics in another thread and then saw his.
And I live in Southern California too!!!!! Orange county
I have several plumerias along my whole front yard. only this one (in the middle) is affected so far. Most of the plant is like this however. It is a well established 10ft tall, 10yr old tree, that came from one of the other plumerias in my yard.
