Thanks for the reply. I've been using happy frog and mixing some kelp and Dr earth's bloom fertilizer. About a cup of kelp and a few handfuls of dr earth per 2 cubic foot bag. Its worked well. Had to top dress a few times. I was asking though so I could make my own soil. I made it and it still needs to cook but so far hasnt burnt my seedlings that I put some in. Its more like 60% coco, 30% worm castings, 10% perlite, and some kelp, happy frog jump start, Epsom, and dolomite lime for calcium and magnesium more than a pH buffer but will do that too. I'll need more p and k in bloom but should get me through veg easily.
