I was reading somewhere that you can tell if you nutrient mix is right for the plant by testing the PPM every day. If the PPM lowers slightly then its OK, if it goes up then the plants is being over fertilized. Is this correct? Any tips on using this method? Also I am using Pure Blend Pro in DWC, my mix is: 5ml Cal Mag, 10ml Liquid Karma, 25ml Grow, 3 drops superthrive (per gallon tap water). The plants are God bud at about 1 month. Does this sound good?
