It is good that you have found out a cause! Now you can begin treatment. General insecticides will be fine, but if you know the exact insect in question, then you can treat specifically for it.

This one might be a little difficult to pin down. I'd go ahead and test the soil for nutrient deficiencies and pH imbalances. If these show normal results, then you might treat for fungal or bacterial infections. I do see a couple of spots on a few leaves, but this may not be widespread.
