I did end up dumping it without brewing it. I figure I am not gonna put all that time and effort into a beer that more than likely will turn out pretty bad or undrinkable. I just cant see brewing a beer I am not going to be happy with when I know it from the get-go.
as far as adding the salts, I believe if you do add them to the HLT, they will be lost because they wont dissolve in straight up water. If you add them to then tun itself, you can be sure that they WILL dissolve in the mash where they need to be. i take it a step further and add them directly to the crushed malt. I think that way the PH will be close from the beginning. JMO
