Yea I personally don't use any snake oils lol. Only the fox farm trio.
I'm not wondering what to use or how much, I was just wondering why there is a guideline of ppm to use when their ppm doesn't match the teaspoons.
Unless I'm reading it incorrectly, the soil feeding schedule says that...

Crazy no one knows why the ppm doesn't match their schedule because I'm having the same issue. Perhaps they say it's "hotter" than it actually is? If that makes sense... I'll be calling the company tomorrow. I know their ppm conversion rate is .7 and I have a Hanna tds reader (.5) but once I...
