Laguna, have you considered vermicomposting? It would be better than adding fresh organic materials to potting mix where they have to be broken down by microorganisms (if present) before the nutrients are in forms available to the plant. The microorganisms can, at least initially, out-compete the plant for nutrients although they release them again when they die. Fresh coffee grounds can also have allelopathic effects on some plants. Not that any of this will change the natural architecture of the plant but just as an aside.
