Flowerslane. Have a look on the underside of the leaves opposite the white spots. Is there a corresponding area underneath with white hairs on it?
If so then it could be Downy mildew. This is very similar to Powdery mildew and just as annoyingly difficult to remove. However, it is not deadly, just unsightly.
