Outdoor hydrangeas can get powdery mildew. It can easily happen in our humid Southern California May Grey/June Gloom days. Should disappear when we have sunnier days. If it’s a heavy infestation some people will remove infected leaves and treat with a fungicide. When it’s happened to mine I’ve just removed the infected leaves and let it recover on its own. But mine was never bad. Yours doesn’t look bad either, a couple of leaves perhaps 🤔. I’d remove the spent flowers too. They’re only a hiding place for the fungus. Removing them will also improve airflow through the plant keeping humidity down. Good luck! It’s a beautiful hydrangea!😊
