Kind of hard to tell with these blurry pics, however it might look like some PM. Not sure though...if you think spider-mites, try looking on the bottom-side of the leaves with a scope.
 
Don’t just think or assume and jump the gun. Get a 120x microscope and look at the leaf, if there are trail marks then u got notes if not I wouldn’t worry so much. You are growing outdoor and your plant is a eco system or soon will be. I am not an experience grower at all, but it seems you need a good rain storm. It solved my problem.
