I mean, you don't need to spend $50 on a meter I don't think. I just got tired of the cheap ones. I'm sure someone will come along and let you know that they have a decent one that cost about $20.

I have one.
$20-30 off Amazon. GET CALIBRATION FLUID.
It says you don't need it. Get their 342ppm cal fluid. Mine was only off by 50-ish. Still, meter is worthless if you don't know if it's accurate.
Meter:
Amazon product ASIN B008SOPO10
Cal solution:
Amazon product ASIN B001VE99X8

8000ppm.... water only. Adjust pH and water only. If you haven't got tip burn then you're probably ok. Let the plant tell you what it likes or doesn't but eh, 8000? phew......

Hanna makes a decent cheap tds meter..
your pen is toast, out of wack, or has something stuck in the electrodes or what ever they are called in the business end of the meter. has nothing to do with ff products.. neither of their popular soils have excessive amendments, just a little raw sometimes.

I watered my oldest plant today with straight tap water that sat overnight. 6.14 PH, 50 ppm No nutrients.
My runoff was slightly yellow, and over 3200.
