Hello!
Thank you for your message.
This appears to be powdery mildew. I recommend taking a sample to your local Extension Office and/or a local reputable nursery to properly identify.
In the meantime, here are some links that should help you not only identify, but also give you some information to control it:

I hope this helps!
