Make your own simple "Ballpark" mash pH assistant software as follows. The three formulas required are highlighted. Follow all 6 listed steps.
NOTE #1: It won't possibly be as good as any respectable mash pH assistant software, but if "Close Enough For Government Work" is OK by you, then this might just be for you. You can do this on paper with a hand held calculator, or make a quick spreadsheet out of it.
NOTE #2: No effort was made to factor in pH drop due to mineralization. Consider this method ballpark OK for moderate mineralization, and tweak as you see fit. No guarantees expressed or implied.
Step 1: Pick pH_T (your desired Target mash pH, this is often 5.4 or 5.5)
Step 2: Guess your beers final SRM color (whereby: EBC/1.97 = SRM)
Step 3: Determine your grists weight in Kg. (whereby: Lbs./2.2 ~= Kg.)
Step 4: Calculate the anticipated pre-adjustment mash pH (pH_M).
pH_M = 5.92-0.035*SRM+0.0003*SRM^2 (whereby * = multiply, and ^2 = Squared)
Step 5: Calculate the grists mEq's of acid or base with respect to your desired mash pH target
mEq's = (pH_M - pH_T)*34*Kg_grist
Step 6: Calculate mL's of Lactic Acid or Grams of Baking Soda to be added to your mash water
(NOTE #3: if the mEq's calculated in step 5 are positive, then add the calculated adjustment as mL's of Lactic Acid, but if the mEq's are negative, then add the adjustment as grams of Baking Soda)
(mL's or Grams of adjustment to add to your mash water to hit your target mash pH_T) = ABS(mEq's/11.7)
(whereby ABS = Absolute Value)

Don't laugh too loud at, or kill themessenger developer please. Rather than laugh at, publicly humiliate, or online kill, please modify to suit, trash, or simply ignore as you see fit. I'm fully aware that mash pH adjustment based upon SRM color has been generally considered a weak method. Judge for yourself how weak. But be civil.
