estimative index... basically means dose everything the plants need (Macros & Micros 3x a week, Gh booster 1x, and optionally Fe 2x) and then do a 50% water change to make sure you don't have a buildup of nutrients that aren't being used.
You can get the package and then you'll still need Ca and Mg. Mg you can get at walmart, it's in the pharmacy section and its called Epsom Salts. It's about $3.00. Not sure if it's cheaper to order it or not. Might also want to get Fe too if you have Fe-loving plants
