What is causing this to my hibiscus?
I am not sure what is causing this damage to my “Dark Mystery” hibiscus leaves. I have looked under the leaves and didn’t find anything significant. There were a few brown insects I squished - at least I think they were and not dirt lol. Can anyone help?

Not sure if this info will help but here we go bacterial leaf spots are caused by lots of different kinds of bacteria and the best course of action is to reduce or eliminate the cultural conditions associated with the development of the disease. In order for a disease pathogen to get a foothold, it needs a susceptible host and the right environmental conditions such as a film of water on the leaf surface, coupled with poor air circulation. Plants under stress tend to attract disease and insect problems, so your hibiscus may be struggling with over or under exposure to sunshine, poorly draining soil, or competition for moisture and nutrients with the roots of other plants.
Try removing the affected leaves (or even an entire branch) as soon as you notice black spots developing. This will remove the pathogens from the area and eliminate the possiblity of them splashing onto healthy plant parts. Removal of leaves and/or branches will also open your plant up to better air circulation, which will allow the foliage to dry quickly after rain (or water from the sprinkler). Finally, try not to get water on the foliage. If the leaves are dry from late afternoon on, they won't be so prone to developing disease problems. Hope this information is helpful!

I don't know what the problem is specifically but the leaves alone look like they've dried out - are you watering sufficiently? You must water until the soil is completely wet. If dried out, water first comes right out the drainage holes and you have to continue to water until it actually leeches into the soil.
I'd suggest spraying the entire plant with Neem Oil. It fixes many pest problems in addition to powdery mildew, which hibiscus is prone to.
Take the leaves to your local nursery. They will give you advice and have the products to help you.

Thanks everyone. The leaves aren’t dried out and it is watered sufficiently. It has to be some type of mite or something that’s eating holes in the leaves. I tried to choose leaves that would make it easier to help identify but that didn’t work lol. I will take other pictures to see if that helps. Some of the replies seem to be cut and paste so I really appreciate those who have answered thoughtfully!
