What are these spots on my shrubs?

[CornishTeaTime]

And how do I treat? One has black spots one has a white milky appearance

Ooo sorry with pics

The black spots look like fungal leaf rot; cut off all the affected leaves and put them in the rubbish bin. You might also need to use a fungicide.

The white spots look like powdery mildew, which is a fungal infection but needs a specific treatment.
