my ppm yesterday was 800 and now its 1070 in a 10 gallon reservoir. is it suppose to rise? and when do i change water or just put in nutrients in the water according ppm?

thanks
 
If you PPM is rising as the water level drops then you need to back off on your nutrient concentration a bit, the plant is not using all the nutes. Change your rez every two weeks completely. Just top off with fresh water between changes.:peace:

Solid advice! I change my res weekly, but I am kind of a clean freak.
