im not asking if i should add nutes now, am asking if that should have been done throught this last run. "IM WONDERING IF I COULD HAVE PUSHED THEM A LITTLE HARDER." im about to flush, this run is over and in the books. im trying to tweek the numbers for the next run. 1400ppm is the recomended level set by GH. 1000ppm is way too low. i'll try testing the runoff and see if it drops below 1400.
