I have a raised bed garden. I've noticed white/yellow scaley areas on a few of the leaves. What might this be?

Thank you for all of the help. This is my first Garden ever! Having a ball:however very challenging. The white/yellow scaley appearance on my cucumber foilage Is due to whitefly.Spoke with someone at a local nursery,showed him cucumer leaf,he directed me straight to this Tomato&vegetable ready to use 3 in 1 insecticide,fungicide,and miticide.You can apply even before problems arise.Here in Az. they suggest spraying every 5 days. Wish me goes!

Sounds like the beginning of powdery mildew. Remove the diseased leaves and discard. You can use one of the Safer organic fungicides to control. With all the wet weather we've been having this is not surprising.
