That is what I was concerned about - I think that I will give it a
squirt with some fungicide to be on the safe side.
I actually have a little one of these planted last fall, I had it in the
pot for a while before. Mine has the blotches too. My experience with
photinia is that (in general) they're pretty frost hardy. I don't have
enough experience with Pink Marble to know whether it's more tender.
However a lot do seem to suffer from black spot, which seems very similar
to pyracantha scab. The problem with photinia is because the leaves are
waxy the fungicide has a hard time "getting in", so multiple treatments
appear to be called for... HTH.
Try adding a drop or two of detergent to your spray mix.
