My hibiscus has white stuff around the buds. The green leaves are small and shriveled and the buds dry and fall off before they even open. How do I correct this and stop it from going to my other plants?
Please check this previous question and answer that could be very similar to your issue (although not necessarily).
The small leaves and buds that fail indicate that they are not getting enough nutrient to perform their function properly. One reason could be that bugs are drinking the sap before they can benefit from it, and @kevinsky response in the other question will help you a lot. Examine the white stuff on your plant carefully and see if it is hiding anything. Houseplant and other gardeners can benefit a great deal from a magnifying glass to see small critters and possible eggs, and a lot of practice examining various plants and bugs up close. Get as much experience as you can.
