ph going up over time?

[mwooten102]

So I've noticed most people's ph seems to get lower over time but mine seems to go up and I'm unsure why. What could be causing this?

More info needed. If your ppm is going down at the same time it could be nutes are too low. Could be many other things also.

Yeah more info. Do you top off your reservoir in-between feedings with higher PH water? Are you using lime or an alkaline substance? It's something you are adding that's raising it.

That's not an accurate statement to make. Many things can cause pH changes without anything being added.

I use a flood and drain system and my ph goes up all the time, I just readjust to desired ph , rarely do I check my ppm's and have no problems with my grow.
