Calamondin orange tree problem

Rabia's picture

I have a Calamondin orange tree in a pot that is developing yellow foliage. It's probably a deficiency of some kind...but what?I was told they need acid soil so I mulched with tea leaves but it seems to have gotten worse. The leaves got gradually splotchy green and yellow. They are also sort of curled up. Anyone got some recommendations?
