I don't have that kind of drop in my rez,. When I first strated some peeps don't empty but half there rez and fill back with water and nutes. I remember that if it drops that much I would use half nutes and water till rez change.

Hi, after mixing a fresh reservoir of nutes (in an aero system), the ppm was 1350. 24 hours later, it was just under 1000. Next day, it was under 800 â?? a pretty weak level for foot-plus plants. Iâ??m a complete newbie to hydro, so I was wondering: should I be replacing what they eat everyday (bringing the ppm level back to 1350 daily), or should I let the plants drain the drink down to ? I read on this forum one opinion that replacing what they eat is good. But logic is also telling me Rating: 5
