So I got this thing to get a rudimentary idea on my soil levels, and it fucking sucks.
So far I've done two tests, about to do a third, and both (as well as the third I suspect) are showing a total depletion of Nitrogen, which I know to be patently false since the leaves are green as fuck and the plants are growing fast. It shows the P and K levels to be in Sufficient-Surplus levels, but with the N levels to be so off, it's casting doubt on the accuracy of those aforementioned two. Other reviews on Amazon have noticed the exact same or very similar trends.
Please tell me I'm just retarded and doing something wrong? I hate when I waste money on garbage.
