Trying to understand PPM better

Trying to understand ppm a bit more. Put in all my nutrients from Fox Farm and they say I should have a ppm of 1680 - 1960, but the ppm meter is really low. Like 300 - 500 it keeps jumping around. Is the ppm stick I got wrong or do I need to some how raise it? I’m on week 4. [image] [image]
