Its been a year since your post so am hoping your hibiscus plants are flowering well. I have two Hibiscus (Rosa Sinensis- Chinese hibiscus) in exactly the same conditions. They flower regularly- almost one flower every second day.
But one of them is giving flowers a size smaller than before. I suppose it requires some fertilizer- but havent added any yet. Have you used any fertilizer that has worked well.
