    This could be a few different things. If you do not fertilize at least once per year, then this is likely the culprit. If you do fertilize, but is high in nitrogen then this can also be the cause.

    I would recommend fertilizing with a well balanced all-purpose fertilizer once per year in spring, Or a high potassium fertilizer once a month or two. Here is an article for more information on the care of these: https://www.gardeningknowhow.com/ornamental/flowers/hibiscus/how-to-care-for-hibiscus-plants.htm

    There must be some labeling mistake on the package. Hibiscus do not grow from bulb. Could you take a picture and post it? I'd like to help, but I'm not certain how to just yet.

    Hibiscus are heavy feeders, especially when forming buds and blooming.
    I would use a balanced fertilizer, diluted in half once a week.

    Give the plant as much light as possible, even using a grow light would be beneficial for a sun loving Hibiscus.

    Here are some links with more care information.

    Your hibiscus appears to have a whitefly infestation. It's hard to tell for sure but the flower bud looks covered in whiteflies. It could be aphids and close inspection will reveal the culprit. The bugs' secretions create perfect conditions for sooty mold to develop. Both can be treated or you can prune out infested/infected branches and carefully monitor. https://www.gardeningknowhow.com/plant-problems/disease/how-to-get-rid-of-sooty-mold.htm
