Is humic acid good for Norfolk Island Pine tree

Question

I have a Norfolk Island Pine tree discussed here. I want to improve its well-being. Would liquid humic acid be helpful? What kind of fertilizer would be most effective? Is there any related documentation to study?

I find Norfolk Island Pines grow too big for a house plant in a few years with only minimal ordinary fertilizer so I would do nothing to increase growth.
