What kind of answer you looking for I never used cutting edge but I know that xnutrients is good stuffOk this isnt the type of answer we are looking for! Screw cutting edge lol im sure you can be a bit more descriptive!
I have used the 3 part + Mag amp, Plant amp, & uncle johns blend in a ebb & flow system and got great results.
Its good for the money, but imo the best bang for your buck is the House & Garden 2 part. I use House & Garden for my soil grows and I'm happy with the results
