Dave, excellent advice. I'm predissolving KNO3 granules. As you were building
up from 2 - 10 ppm (I'm trying to build up from zero to 5) were you making
measurements of your results say, an hour after dosing, or 12 hrs. after the
plants had devoured the NO3? I.e., I'm not sure if I'm aiming for 5 ppm and
hour after dosing in the AM or 12 hrs after dosing.

Thanks, Sharon
