Willow oak dropping leaves
My old willow oak is dropping its new leaf growth. Its unusual and has never done this before. The underside of the leaf has tiny brown spots on its underside. The tree has never had this problem before and it is unusual. Tje tree is 75 to 100 feet tall. Any guidance will be appreciated.

We have been swamped by reports of cold damage on a huge variety of plants, including trees. Even, specifically, willow oaks. You do not need to do any treatment.
