Yellowing Leaves On Hibiscus Plant

Is it too much water – plant is in sun and blooming profusely?

Answer 1

Unfortunately, your photos did not come through. I am unable to see the damage. Too much water is one of many reasons to see yellowing leaves. I would test the soil for as many factors as possible to know for sure:
