Hey i've got this problem with the hibiscus plant?
From what you describe the thought of aphids comes to mind immediately. Treat aphids with a stomach poison as the little critters are suckers.
Aphids, or plant lice, are small, soft-bodied insects which are common pests of nearly all indoor and outdoor ornamental plants, as well as vegetables, field crops, and fruit trees. There are hundreds of different species of aphids, some of which attack only one host plant, while others attack numerous hosts. Most aphids are about 1/10 inch long, and though commonly green and black, they may be gray, brown, pink, red, yellow, or lavender. A characteristic common to all species is the presence of two tubes, called cornicles, on the back ends of their bodies. The cornicles secrete defensive substances. In some species they are quite long, while in others they are very short and difficult to see.
Aphids feed in clusters and generally prefer new, succulent shoots or young leaves. Some species, known as woolly aphids, are covered with white, waxy filaments which they produce from special glands.
In some situations ants tend aphids and feed on the honeydew aphids excrete. At the same time, they protect the aphids from natural enemies.
