Cutting Edge nutrients

I am using a nutrient blend called Cutting Edge Solutions, made in Santa Rosa, Calif. They were highly recommended by my hydro man. I also bought two additives made by Cutting Edge: Plant Amp and Uncle John's. I've gotten some guidelines and recommendations from my hydro guy, but i would like to know if anyone is familiar with these two products (Plant Amp and Uncle John's). I am looking for anyone else's usage guidelines or recommendations on these two products, i.e., how often to use, how to apply, at what stage to use each, etc... Thanks for any feedback!
