I got this Meyer's lemon online Oct 2016. After it arrivals, it slowly loses its leaves. Nov last year I moved it an artificial light grow tent. It had some mites issue and continue to lose its leaves. Now it lost ALL of its leaves. Just before I am going to throw it out, it starts flowering, but still no leaves.
Should I keep it and what should I do make it grow leaf again? I never thought this can happen to a citrus tree. This is stone fruit behavior
