Indoor calamondin orange tree

I am so green at growing, and my poor indoor calamondrin orange tree is suffering due to my inexperience. Cal, yes the tree is named…has its own personal grow light, well drained soil, a water meter to alert me when it is thirsty, has been fertilized with citrus feed once this summer, and yet still looks like a Charlie Brown Christmas tree.

Please, oh please teach me how to make Cal a beautiful tree.

 

Does Cal receive any additional light or is this someplace that is relatively dark in the living space? The leaves closest to the light look healthy, but the bottom branches are too far away from the light source (if it is the only significant one) to maintain holding on to the leaves.

 

Thank you Daniel for your reply. I’ll take Cal on a field trip outdoors as I live in a subtropical climate and see if some fresh air will lift his spirits and leaves.

keep in mind you must change light levels gradually. Taking it straight to sunlight will burn all the leaves...
