    possibly leaf spot....that is the closest I can get :)

    I would cut the diseased areas back since it is about to go dormant anyway

    Based on how the flowers behind it look....it looks like everything might have been overwatered and got some type of fungus.

    Looks like textbook salt burn to me, old growth is effected, new growth is OK. Also looks like some powdery mildew on the miniature roses and zinnias.

    Watering too frequently, not letting things dry up a bit between waterings is the cause. if you can get some compost tea or some type of organic acid or Alka-Leache drench it with any of those and then let it dry up. Then change the water schedule

    Another tip for great Hibiscus is treat them like Roses. Fert with Rose fert same schedule and cut them back in the spring.
