Your numbers look okay to me except for pH and TA. You could get some arm and hammer WASHING soda (laundry aisle). It will raise your pH and your TA. I would try 2 cups and then test. If you need more, add a cup and test again. I would aim for about 60 for TA and 7.4 or so for pH. If you can't find washing soda, you can use borax (raises pH) and baking soda (raises TA).
