Pieris Red Spots

What's wrong with this Pieris and what can be done with it? Some sort of leaf spot or rust? Thank you!

I think it's some kind of stress, possibly an infection ?
Are they in ericaceous compost/acid soil ?

I'd agree. It's most likely to be a cultivation problem. Lack of nutrients probably. They need neutral to acidic soil to do well.
Although - all evergreens drop leaves, so it isn't necessarily a major problem. Have you got a pic with a wider view? That would help, as well as any other info about how and where it's growing

Just found a pic from August. Seems no spots then. It's in a small raised border. I suspect it's been planted in to whatever soil was originally there and left to its own devices. Perhaps I'll suggest some ericaceous feed and take it from there. There is a small camelia there too which may appreciate the same. Thanks @Fairygirl @AnniD D

I wonder if it's just too dry and sunny there. If lavender is doing well - it suggests that.
Both Pieris and Camellias prefer a reasonable amount of shade, and cooler, damper conditions. Raised beds drain more quickly too, so it may be something that simple.
