I have recently been contemplating trying advanced nutrients product line. I have heard nothing but great things. I am currently using plantlife products 3 part with a bunch of additives. This current system works outstanding but is a bit costly. So my question is, with advanced nutrients do i need all 13 additives and the two part sensi to grow outstanding marijuana? Or just a few of the additives? they are separated into 4 different groups. hobbyist, expert, professional and grand master. Do i need all 13 additives included in these groups our just certain ones, and if so which ones? Does anyone have an advanced nutrient chart they are using that they know works outstanding?
