Hibiscus: red capitalio, 1 by AuntAnne

Last year at the beginning of the season this beauty (a few years old) was nice and green and blooming profusely. Then out of the blue the leaves began to develop yellow spots and die. The new leaves that it was putting out developed the same spots and died before getting very big at all. Needless to say there were no blooms anymore. I re potted it into a larger pot, moved it, fed it, babied it, offered nice encouraging words and still nothing. After winter, it was leafless. I bought some leaf hormone and it began putting out leaves. But they are now and still turning yellow spotted, it's just a matter of time before they wither and die. What is the problem? Does anyone have any suggestions? Anne

P.S. It's a bit blurry but you can see the coloration problem.
