I am using pressurized CO2 on all of my tanks. Two of my soil tanks have lots of stem plants and I've been dosing small amounts of potassium. Other than that I might dose excel just to add a little extra carbon insurance.

I did setup my soil tanks a little differently than the walstad method though. I added natural clay to the soil to add iron and help bind nutrients better.
