There are many things that can cause this, but I would look to see if there are pests on the leaves. Typically, these pests are very small and will appear as small specks on the bottom of the leaves.
Regardless, treat the plant with both a pesticide and fungicide. This will treat just about everything that could cause this. I personally like neem oil for this. It is both a pesticide and a fungicide and is also organic.
