Bruh, obviously we are agreeing to disagree. Just follow this journey. Maybe you'll get something out of it. Maybe you won't. Maybe it will confirm what you already know. Ask questions if you don't know. Did you ever once ask what my final ec was? And what is yours? Or do you just go by ppm? How's your water temp? Chiller? CO2 levels? It's ok, I'll address ask if these items. Thing is, it can be used at any scale.
