It would probably work, but not the best. The problem with bone meal is that it doesn't have any potassium (K). I don't know what having little to no potassium will do to a grow, but I know that having high potassium will do wonders for your grow. There are many sources of K, but the only organic ones I have ever used are greensand (takes forever for it to breakdown) or wood ash (raises soil ph). Why don't you try just bone meal and see what happens? Let the world know.
