1080 ppm in the res its hydro
Sorry guys, my bad...:o
Piglet, my question was for the OP, greentrich. What I'm getting at is that unused nutes may be building up in the pots. That can cause the pH to drop as the nutes get more concentrated. If that's happening, though, the runoff water will be high ppm's...simple!:thumbsup:
This was actually kinda for you:
because that's what happens as they become more concentrated. (It also happens in a hydro rez.) If you're feeding more nutes than the plant can use, it will use water faster than the nutes (duh) and the nutes get concentrated as you keep adding them at the same concentration.Quote:
Acidic ferts get to be stronger acids
If you add non-nuted water to the res and the ppm starts to "correct" itself, that's what might be happening. (The pH should correct itself a bit, too.)
But we shouldn't jack greentrich's thread. You should post a question in the hydro forum and the experts there can help you.
Greentrich, I haven't used that combination coir product so I don't know if you can "pretend it's hydro" like you can with straight coco. But I run coco as low as pH 5.2, no problem. :thumbsup:
Why are you adding peroxide? You know the pH is < 4, right?Quote:
an occasional small dose of peroxide
