I've used just about every nutrient line out there. They all pretty much work the same as each other. Only one of them I had problems with and that was advanced nutrient line. Could have been something I was doing wrong but I've not had any trouble from any of the other nutrient lines. I'm currently using Emerald harvest. I've used General Hydroponics a lot it's a good one. Dyna-grow is another good one, but like I said they are all bout the same to me sept for advanced.
