AJ and Martin both regularly monitor the Science forum, and are incredible resources for water related questions, besides being patient beyond belief.
Before anyone else does, you are advised to read the sticky in the Science forum on water treatment, and obtain a water report from your supplier if you have not already..
Having said that, I generally have to acidify my sparge water a hair more than my mash water, due to the absence of grains affecting PH.
If your mash PH is coming in that low, I'm wondering what the composition of your water is, nd also curious if you need to acidify at all. Hopefully one of the water guru's can chime in here, good luck.
