Botanicare's CNS17 line got my attention because it is "one part" for each stage of the plants life. With that being said, the nutrient line does not perform well for cannabis if you are just mixing in with water as recommended on the label NOR does it work following the nutrient calculator. *Side note: I have tried contacting Botanicare numerous times by email, and have NEVER received a reply from them! Just saying. I the end, because I bought a gallon of Grow, Bloom and Ripe, I calculated the individual PPMs of N, P, K, Ca, Mg and S in the individual formulas and then used a spread sheet to manipulate the amount in mL needed to hit the ppm range I was looking for in Veg and Bloom. It was a lot of work and so far I have only tested it on a DWC basil project, but, that shit is blowing up!!
