| Depends on what it is. For that more info is needed. Looks it could possibly be sunscald but usually the patches are more uniform. Possibly powdery mildew if the white patches are furry. Could be leaf edema due to heavy rains or over-watering. The patches start out green and puffy and then the cells die. Could be from pests. Any sign of aphids? Dave |

| Hi Dave, this is the only plant out of 6 with this ailment. All are the same variety and age..The patches look furry to me, then fade as the leaf dies. |

| Last pic sure looks like powdery mildew to me. Fungus spores are visible. Strip off all affected leaves to help slow the progress. Treatment is fungicides. There are both organic (copper, sulfur, Neem oil) and synthetic (Daconil) fungicides available. As to homemade concoctions, some claim a diluted peroxide spray 1 part to 10 parts water will help. Others claim sprays made from baking soda or aspirin also work. Personally I have never found them to be very effective. Dave |
