Mash ph is low 4.6 what's best way to raise not having chalk I knew I would forget something I was worried about being high and didn't consider being low
The strips are useless- I just don't believe your mash pH is 4.6. If you post your recipe, and your water and additions we can see if that is at all possible. It'd be hard to get a mash pH of 4.6 unless you did something extraordinary like dump in a ton of acid to a grainbill with lots of dark roasted malts.
I generally go with more modest amounts of ions than Tasty's profile is. I have most of my IPA recipes with 150-250 ppm of sulfate, and calcium under 100.
