    I would be willing to bet that even though you did not see pests, the plants still has a pest infestation. If it was a disease, it would likely not regrow leaves. Some pests,like thrips or mites, can be difficult to see with the naked eye. I would treat the plant with neem oil. This will kill any harmful pests on the plant without being a danger to people or pets in the yard. Here is more information on neem oil:

    Is this a tropical hibiscus or hardy hibiscus? If tropical, mine that are in full sun are doing the same thing. Are yours in a pot? If you are experiencing great heat and no rain, I think it is just suffering as a result. Be sure to water well and you may want to move it to partial shade during the hot times of the day. They won't bloom as well but they live for another day (Fall). YOu can then get it to survive to bring into the house this winter (if you get frosts).

    Some leaf loss is normal for a hibiscus as long as it looks healthy overall. You can reduce it a bit more by giving it some fertilizer and increasing watering for the plant.

    Leafy plants naturally discard the oldest leaves so a few yellow leaves on a hibiscus is natural. The plant is simply making room for the new growth. I pick two or three yellowing leaves off my hibiscus every other day. I have a lantana that has the same habit.
