Selling nutes is a big business. I keep it simple too.I do my own soilmix, that keeps all the bennies inside( fluvin /huminacid). Iam no expert in Soilless but ive seen impressing grows with just 3 Components , Calamg, one veggin fertiliser and one blooming fertiliser. And maybe drip clean. I see no big reasons to use 10 bottles for a" hobbygrow" and then flushing it . I see a big problem in usig to much fertiliser, while growing. and after growing contaminating water and ground with the waste. But thats only my opinion
I only see benefits for using it in soil
