There is a new product, X-Nutrients, that when I called them up, they said that I could use them just as I use my current product, (Fox Farms). I have been using it the same as I do with FF, on a couple of my plants, just to make sure, and so far, I haven't notice any differences. I am going to keep up my experiment to see for myself, all the way to the end, and then check the 'Differences'............ Of course, I'm soil by the way....
