Your plants couldn't handle full strength? Why wouldn't you simply dilute a bit more? If you call their Tech Support that's exactly what they'll tell you, though it should be pretty obvious that's the solution. You shouldn't need the Cal-Mag, either.
It sounds like the pH Perfect worked fine, you just didn't listen to your plants.
I cant say the nutes suck, cause my girls got WAY Bigger than I would have expected to the point of being TOO Big for my 400w light.
So you thought the nutes were too strong, and you won't use them again, but your plants got way bigger than usual? Sounds like a terrible problem... if you're looking to grow small plants I can recommend quite a few nutrients to accomplish that.
I also don't understand the confusion and debate over whether the nutes are buffered. Of course they're buffered. Why is that even uncertain? They are. Every decent nutrient is buffered. Every decent nutrient line is chelated.
What's different here, as far as I can tell, is the degree to which the nutrients are buffered and chelated, and they've made sure everything else in their line doesn't interfere with that. If you chelated all of the nutrients enough you could theoretically grow plants at any pH that wouldn't physically dissolve the roots without seeing pH lockout. Chelation makes a nutrient (macro or micro) more easily absorbed, meaning that it can widen the pH range at which that nutrient can be effectively absorbed by the plant.
So if you combine extreme chelation with a strong buffering system you end up with nutrients that are nearly impossible to screw up pH-wise.
People may not think that's ground-breaking but the simple fact is we only have one brand of nutrients that's done it. If it were easy, they'd all do it. So there's clearly some kind of obstacle that Advanced Nutrients has hurdled that the others can't or won't.
