I would like help to fill out these expected results for different conditions. Point of this would be to easier see which parameters are relevant to different problems. The question of how much or how little is also topic for discussion. We could set a standard and call it medium as usually, to much or to little of something is not good. Medium would be:
N: > 0 < 1 ppm
P: > 0 < 0.02 ppm
For instance, medium nutrient and medium light gives good growth and good colors. Obviously there are other general factors that needs to be stable and within range, and they should be checked first:
Sg: ~1,026
pH: 7,9-8,3
kH: 8-12 ppm
Ca: ~400 ppm
Mg: ~1300 ppm
N: > 0 < 1 ppm
P: > 0 < 0.02 ppm
