I wonder if GH builds in for tap water with their PPM estimates or something, because I always come up low on PPM's / EC when I add every single thing they say exactly.....By quite a lot...Like 20-25%.I'm guessing your Vivosun is just fine. My EC pen from 2011 or was it 2014 that I got off ebay is still going strong
The other possibility is I got some bogus watered down nutrient from somewhere (Amazon).
We shall know tomorrow.
Now, for a meatball sub. Just gotta go get it, lol.
