  1. I did a Rez change yesterday ppm was 850 12 hours later it's down to 690. Is this normal to drop that fast? These are in a outdoor hydro setup.
  2. check again. check ph, check water temp. are u uaing ro water?
    anyhow if ph or temp is wrong adjust.. give it a day see if its still dropping.. if ec drops and ph rises it pretty much means u can feed ur plant more nutes.. if ec rises and ph drops then vice versa, ur plant needs less nutes..
