K - Potassium GANS
You can basically produce Potassium GANS with the Caustic (NaOH) or CO2 GANS Method or can use the Replication Unit to make Potassium GANS-water.
Sources:
Pumpkin Seeds are a natural source with Potassium (but also have other elements in it). Look for other natural sources too.
Nutrinos from the pharmacy.
(Also you can use salts of K too, for producing this GANS or you add already at the Nano-coating process 20-30% KOH to the NaOH (80-70%). Don't forget, that the fields are now captured in the Nano-coating. If you want to produce other GANSes, or normal CO2 GANS, you have use Nano-coated plates/wires with NaOH only!)
