Wind burn from fan?

I have noticed a few leaves that are developing a strange narrow path of slightly tan/brown discoloration, approx 1/4 to 1/2 in width. I was wondering if anyone had some pictures of wind burn on a plant. Im not entirely sure whats going on yet but it is one of a few things on the list that im trying to cross off. 'process of elimination'. Thanks for your help!
