My hibiscus plant used to give really big and yellow (dark pinkish almost magenta shade in centre) flowers but after a month the leaves began to curl inwards and the buds started to fall off before blooming.. i removed all the leaves and thought id let new healthy leaves grow back. I can see new growth but the flower size has reduced immensely. They're much lighter in color too. The first picture is when bought it and in the second picture.. that's how it is now. I gave it some DAP and compost two weeks ago. Please let me know whats going wrong with it.
