Ah man. I feel like the kid with his fingers in a leaky dike. Just when one problem gets plugged, here comes another one. I need to lower ph and raise TA. Here are the results:

20k IG colored plaster
FC: 1.5
CC: 0
TC: 1.5
pH: 7.9
Alk: 100
Cal: 190
Cya: 50
Temp: 78 F

So, after reading the sticky, it appears I have to add both baking soda and "ph minus". Should I adjust for ph or TA first? I assume it's futile to try fixing both simultaneously. Any advice appreciated.

Cheers from the Sierra Foothills,
