The PH of my nutes is a little high, 7.5 to be exact, i plan to use vinegar and bicarb as buffers, is there a neat little app that can calculate how much I need to add, i found a great one for mixing nutes to the strenghth you want - if there isnt one then can one of you stoner codemonkeys write one please, you would be my hero. For a quick fix I need to know how much vinegar to add to bring 30 litres down from 7.5 to 6-6.5, but would love a little app so I can quickly calculate it myself next time. I have searched the forums but could not find anything specific.
 
I figured it out with a bit of trail and error experimenting. I found 1 mL vinegar brought 3 lts solution down 1 pH point.
