This article refers to powdery mildew which is common on cucumbers. Your photo though seems to have some other white stuff. Can you send a closeup of the item? 
There are many useful articles about cucumbers online. Add “edu”or “extension” to your word search for reliable resources.

Looking at the photo again it looked to me that it could be leaf scorch from exposure to a hot sun on new leaves. Just a thought. Did you harden the plant by gradually exposing it to the sun over a week? Or was it grown from seed?
