hibiscus help

My hibiscus shrubs are 8 yrs old. They grew at normal rate, until the budding cycle, the leaves around the buds are curling up. No mold or mites but I did spray them with mild soapy water. Also gave them some Miracle Gro. I read that potassium is best for them. Any help would be appreciated.
