Could be angular leaf spot caused by a fungus or bacterial leaf spot caused by a bacteria. Need to look in a microscope to tell which one. Management of this problem would be best with starting with clean uninfected seed and copper type sprays that would be considered organic if that is the goal when symptoms first appear with some weekly applications if necessary and the disease may or may not progress depending on weather.
