Photinia Red Robin Leaf Problem.

Question

I bought a little red Robin lollipop tree about 18 months ago,the leaves became pitted, I followed advice sought to reply which I did, it seemed to do the trick, whatever it is it’s back again but worse, pitted, dark and blotchy leaves and leaves dropping off. I have been reading up about fungus bit can’t say for sure. Can you advise/diagnose please, I need to treat whatever is wrong with it.
