Hi John, flower-bud dropping in hibiscus has many causes. Maybe over fertilising – you didn’t say how often you fertilise it. Twice a year would do…September and February; and stick with Osmocote liquid Citrus fertiliser. Some Hibiscus varieties (especially double flowering types) are very prone to bud dropping. Maybe move your plant to full, all day long sun and pot it up into a larger pot with Osmocote general potting mix. Good luck, Don
