Nope.

How is the plant doing in general?

Let's see an image of the entire plant or, at the very least, a much larger portion of the plant.

Here is the plant. In general there is new growth, and a fairly healthy green, other than the one branch with several leaves, nothing else seems affected. Likewise, adjacent plants aren't affected. Can't figure how to get more than one picture into a message so I will send a picture of the top of the leaf as of Yesterday. Bronzing appears to have increased a little. No other leaves affected other than ones on the one branch. Could have sworn that other leaves were involved, but couldn't see any today.
