Also, I didn’t realize I should subtract my water EC from the fertilizer/water solution EC to get to the appropriate level for feeding. Am I understanding that correctly? Say I am supposed to feed 1.0 EC, and my water is 0.5 EC, then my feeding solution should be 1.5 EC? (my cheap TDS meter says my water is 310 ppm / 0.62 EC).
This nugget is particularly helpful though. “EC of drained water – original EC = excess EC... and
Original EC – excess EC = EC value for the next watering”
The one article says soil based grows don’t have to worry about water EC as much. Obviously there would be a limit to that. Hoping that’s true because I don’t want to purchase a RO system.
I’m taking water samples to a lab tomorrow, so I’ll probably have some questions about that at some point. I’ll start a new thread tho so I don’t blow yours up haha.
No i include my well water .3 ec. The full ec is what the roots see.
Alert me to your thread when you do it. I would like to see what you come up with.
