Citrus Leaves - White ... stuff?

Need help identifying this white stuff.
I installed citrus on my mother's property awhile back, and she sent me these photos wanting to know what this white stuff is. No, it's not a web. It is a Rio Red Grapefruit tree.

Looks like powdery mildew to me.

She says it appeared right after a mild rain.

looks kinda like residue or hard water to me. Dried up rain water should be clear. Do you have sprinklers near by or have you used a foliar spray recently?

Was that the first rain in a while? It looks like dust that has washed off the leaves and collected in the upturned leaves that are able to trap water. I see this after a rain with my citrus.

She said she has been without rain for awhile. Dust and dried foliar spray rinsed down sounds right to me.
