Well the CAL-MAX I put in that ammount because I have to get from 0 ppm to 210 ppm (EC 300) which is what my nutes are optimized for.

Last night I actually re-added nutes and CAL-MAX for the first time because my ppm reading went down since I changed the tank.

I figured my plants would eat more nutes because I didn't add all the additives, just 60 ml of CAL-MAX, 28 ml of H202 35%, and 280 ml each of Bloom A & B.

Do I keep the ppm the same as when I first add nutes at tank change-over? Should I re-add CAL-MAX during the week; and how much?

Thanks again.
