I have the same thing on my squash and cucumber leaves. I also have those annoying white flies all over them, so maybe it’s from the pests or a moldy fungus.

It’s powdery mildew. It’s very common. It can be treated with neem oil or a mixture of baking soda and dish soap diluted in water and sprayed on the leaves. It’s usually a sign that the leaves need more airflow and/or the plants watered from overhead and not having enough time to fully dry during the day. Any combination of those things can bring it on. It’s a soil-born plant disease, so it can be difficult to avoid, especially in regions like the PNW, where I live.
