So I'm new to this. And I'm unsure about a few things on creating an organic soil. I have my perlite, my peat moss, and my ewc. (no compost, should i?) But before I buy my amendments what are the NPK ratios for amendments like crab meal, alfalfa meal, neem seed meal, granular azomite, and kelp meal. all from down to earth. and I'm gonna use it from start to finish. possible? with right amendments and right NPK ratios I believe it's possible.
