What’s wrong with my gardenia?

This gardenia plant is in a planter in the front yard. It has been acting this way since the end of last summer, and I'm not sure what is going on. I have been giving it acid fertilizer every few months or so. I do not think it is a lack of fertilizer. I live in zone 10b.
