Sensi Grow Part A & B

So I just picked up these nutes for my 5 gall DWC buckets. The bottle says a dosage of 600ppm and the online nutrient calc is saying 1040 ppm for weeks 1-4 of vegetative growth. Isn't this way too high? I was under the impression that around 300 would be good for clones, which is what my clones are currently at. Should I raise the PPM's according to the calculator or keep them low?

don't use what the directions say. i suppose u have meter just pour in a small amount, test it see what it is and adjust accordingly. Or just go with 1/4 the directions say
