Just wondering... after dropping 160 litres of nute mix by almost a full 2 points with just 10 ml of GH pH down... wtf!!??

...is the potency different between different pH down/up manufacturers?
... does ppm or EC strength of nute solution have an effect on pH adjustments? IE does a higher concetration of say 10 gal nute mix need more pH down than a lighter concentration 10 gal nute mix to make the same adjustment?
... does temp or constant temp fluctuations have an effect on pH?

New to...
