Although a biggy, CO2 is the one I'd keep track of and the NO3, perhaps the
PO4 if you don't add any. I think folks can get away with that since testing
for K is not the biggest issue nor PO4 as long as there's some present. Fe
is a ball of prickers and I gave up on direct quantitative testing
approaches for qualitative approaches. The push pull effects of NO3 and PO4
are interesting though.
