Your water probably wasn’t conductive enough. Try adding some salt to raise the ppm and it’ll read correctly. Wet soil is way more conductive than pure water.

Just tried, and with about 2 teaspoons of salt in a half cup of water it reads about 7, or just at the end of the "moist" but not quite "wet.". So better, but I think the meter just isn't all that accurate. (I don't think she paid much for this thing anyway... or at least I hope not.)

Almost any salt will work, actually. It could be table salt or any NPK salt that is used as fertilizer.

So, if there is a farmer that is really pissing you off, dump several hundred tons of NaCl on his fields. Nutrient spot tests might get temporarily fooled and everything will also die.

Remind me to never piss you off...
