Yeah I'd try making your own super soil. I use sub cools recipe, but I hear NV has a great recipe that a lot of growers here use and have great success. I personally start with FFOF and add light warrior to it. Two bags of ocean forest to one bag light warrior, then mix in my amendments and water it with ph'ed water, then let sit in at least 75 degree temps for at least six weeks to cook, or chelate all of the ingredients. I add mycorrhizae, sweet lime, Epsom salt, worm castings, composted cow manure, blood meal, fish bone meal, high P bat guano, azomite, and humid acid. Now this mix is hot so If I put clones or seedlings in it it'll fry the bejesus out of it. So I just put about 4 gal in a 7 gal pot. And then add regular unamended soil to the top and kind of blend together where the two soils meet, so my plants don't burn and slowly adjust to the hot soil. Then all I do is water through veg and flower and get great results. If I see any deficiencies I just make up a tea and water in. Hope this helps.
