how do I bring my hibiscus back?

Question

I purchased a hibiscus that was received off a truck as damaged. The cooler had not been turned on the entire trip from Florida to Pennsylvania. The plants were molded and rotting. I purchased one at markdown as damaged, cleaned it up, repotted it and it flourished. It got blossoms all over it and thickened with leaves. It’s been 2 months now and the leaves are turning yellow and dropping off as well as unopened blossoms. The weather, from what I have read on them, shouldn’t be the issue as it has been a very warm summer and I keep it watered as I should.
