Choosing Soil
We recommend brands such as Klassman KT2, FoxFarm Ocean Forest, Pindstrup Universal, CompoSana Universal/Flower/Bio or Plantacion (Spain), FloraGard Vital Blumenerde or comparable FloraGard soil mixes for flowers/plants. Use a seedling mix for germinating your seeds.
Worm manure and compost is a valuable additive (use 15-20% in your mix).
Heavily fertilized soils like Bio Bizz All-Mix have shown not to be suitable for indoor grows. They contain too much nitrogen, have an extremely high EC (salt) level, and are better used for outdoor where the plants have a longer growth period.The Light Mix offered by Plagron and Bio Bizz is extremely low in nutrients and completely unsuitable for any natural soil cultivation.
Further details and more product suggestions are available in our
SOIL GUIDE.

K:300-500 mg/L
above I copied and pasted some info provided by the mandala seed web site
it describes a range of whats likely in your soil out of the bag
so thinking out loud
so would you say it sounds accurate to say
if I start a seed in potting soil and then re-pot into foxfarm (hot mix) and the water it in im sure the run of would show a much higher EC than the plain water going in
since id be pushing the nutes already in the soil out with each watering the waste should naturally be significantly higher than the feed water in the case of soil???
for this reason relying on the run off EC isnt appropriate
