because it's 1% N and 5% P2O5

It's because it's phosphoric acid. That's hydrogen and phosphates.
H3PO4
pH up and pH down are food. You could also use nitric acid for N, or sulfuric acid for S.
pH up is almost always potassium hydroxide, which sources K.

For some reason, classifying your product as a pH up or pH down exempts you from having to provide NPK values, or percent of anything on it.. so most products don't list anything about the concentration.
does anyone know the NPK of Advanced PH down? cuz I can't find it...
also GH doesnt seem to list an NPK on theirs.

yep that makes sense. just never really thought about it, I use Advanced ph down mostly, and it doesn't have an NPK on the bottle. Wife came home with ph down from DG with an NPK on the bottle, im like "uhhh!" ...and it takes a lot more volume. Why don't Advanced or GH put the NPK value on the bottle? is it derived from some other source?
*edit:
you already answered this, so thats crazy as hell! at least with advanced it barely takes any, but some of these take ounces and ounces, wowzer
