mixing your own soil, from scratch where you know EXACTLY what is in it, and then you just gotta use water. sure, teas will help, or foliars(spraying diluted-strength fertilizer on a plants leaves)..but in an organic supersoil, it becomes a lot easier...and you can reuse the soil after each grow, and it keeps getting better, as long as you re-amend it!
good luck, hope this helps you make the deciscion you feel is best
