I think you should pat yourself on the back then, instead of your nutes!
The more I read the more I see that all the nute brands are pretty much exactly the same. Plants take up the nutes they need with ease as long as the PH is in range and there isn't too much of an imbalance.
The main ingredients are calcium nitrate, potassium nitrate, potassium phosphate, magnesium sulfate, potassium sulfate, sometimes ammonium nitrate and a range of micronutrients which are either sulfates, or chelated.
They all contain these things, and I really think it's all in the setup and environment, all in the grow itself. AN sure is great at advertising though!
I'm switching to single part ionic grow/bloom as soon as I'm out of what I've got now, and ditching all the additives except maybe a bit of bloom booster of some type for flowering.
