Al, what is the correct way to top off a nutes tank?
I lose about 2 gals a day in a 20 gal tank. So i add back the 2 gals then ph adj the whole tank. Im thinking that that is causing a serious problem, cause by day 7 i've add about 10 gals of tap water with ppm of 170, and diluted my nutes strength from 1400 down to bout 1100. Im starting to think that im turning my tank into hardwater and probably locking out other nutes, because in the 2nd week of the same nutes, all hell breaks lose (new leaves/shoots turn limegreen more and more everyday, leaves start to taco up, growth slows down to a halt, etc.)

Should i just top off back to 1400 ppm and then ph adj?
What happens when im down 2 gals and my ppm still reads 1400.. Are my plants drinking and feeding at the perfect rate? Do I not top off?

Thank You.
