Thank you for sending us your gardening question. It could be a leaf blister fungus or a bacterial infection. Fungicides should be applied before the onset of disease so the best you can do now is pick up any fallen leaves so as not to spread the pathogen. Avoid wetting the foliage when you water. Also remove those three affected leaves in the photo. You can check the undersides of leaves for pests such as aphids, whiteflies, or scale. They suck the plant juices and can cause curling and leaf deformity. These articles should help.
