I use the same nutrients as you. I use to calculate the mix, now I just put in how much I feel it needs. For the first 3 weeks, id just use 2ml
calmag, .5ml micro, .5 grow, .5 bloom, 2ml
hydroguard, PER GALLON. So if you have a 5 gallon bucket, add 4 gallons of water, which is what I did in dwc, then id add 8ml
calmag, 2ml micro, 2ml grow, 2ml bloom, and 8ml
hydroguard. . that should be about half your suppliers recommend dose, and it should keep your ppms below 300. Since your not running enzymes or flower additivies, or buffers you will be fine with low ppm. Airstones 24/7 below netpot, and I like ph 5.6 float up to 5.8, lower back to 5.6. . and so on.
