Yellow spots on Oregano, Rosemary and Mint
I keep getting yellow spotting on all my herbs in my herb garden.
Everything is planted in the soil. They get full sun for 2/3's of the day, there is no shortage of water and I have tried applying a general fertilizer with no success.
I feel like this must be some sort of soil issue as there are no obvious pests the undersides of the leaves.
The oregano in this picture is fresh growth and it always gets worse as time goes on.
