I use RO water. I had it tested by Ward Labs. All stats are configured in my BF settings. My estimated mash pH in Brewer’s Friend consistently comes out lower than actual. My meter is two-point calibrated in known solutions. 6 brews in a row my estimate is off between .15 and .20. For example, today’s brew was planned for 5.3 pH - using brewing salts and lactic acid. Actual mash pH was 5.46. Any suggestions to get closer to target (other than overshooting acid additions)?
