Many folks have ended up going back to TMG.
As far as macro nutrients, it does not matter, NO3 is NO3, PO4 is PO4, K+ binds with no organic molecules, so it's the same, Ca++, Mg, SO4, Cl etc
Does not matter where it comes from, it's still the same stuff.
KNO3 runs 15$ for 50lbs here.
Why should I buy it diluted with a name brand on the the bottle and pay extra for water/shipping?
15$ is what one little bottle of the ADA cost, and the 50lbs will last till I have grandkids and they have planted tanks. I also know precisely what is in it, KNO3, pure and simple, a dosing calculator can easily help anyone dose it dry.
I've been testing a new trace of my own design.
It'll be about 10-20X cheaper than Flourish and TMG.
And it'll be sold dry via Greg Watson etc.
Unlike the macro nutrients(other than say Mg), chelators vary in the name brands as do the ratios. Few measure the other trace metals other than Fe.
It used a mix of chelators, a weak highly bioavailable one and stronger longer lasting one, and unlike just Fe, these same mix of chelators will be applied to all the trace metals, not just Fe only.
Plants all use the same building blocks so delivery is all that's left.
Chelators that are specific for the KH's we typically find can do this easily.
At that point, I'm free of any name brand, cost 20X less, easy to determine concentrations, cheaper to ship and grows the plants better.
