A bit of a general question. I'll see what I can do. There is a Roots Organic soil that contains plenty of nutrients for the first 30 days, then there are liquid nutrients (what I think you're talking about) that you use in the Roots about after the first month...however a few of my friends have used the product with varied results. One grew it with no problem, and produced some chron - 8.5/10, while the other got a disappointing 5/10 (he had a lot of issues with it, not sure exactly what happened, just smoked the same strain/soil two different grows )
