I'll just add my 2 cents since we have so many Hibiscus and are used to their symptoms.

Hibiscus like acid......yellow leaves are usually a sign of lack of nitrogen......if you have acid food....you can use it, but we do natural.

We use home made compost mixed with coffee grounds to bump up the nitrogen. Cheap and very effective....just top dress and water in. Our compost also has peat moss mixed in it. We call it com-peat. So com-peat and some coffee grounds. Starbucks gives used coffee grounds away free if you don't drink it.
