Has it gone below 60 at night? Hibiscus is sensitive to temperature. Your plants look healthy and it looks like it is blooming. Hibiscus flowers only bloom for one day, sometimes two. The plants are short and very bushy. It is not what I am used to seeing. Hibiscus will rapidly grow to over 10 feet in a few months in the ground or a large container. They usually need more nitrogen and potassium but not a lot of phosphorus.
