Last DWC grow i was using ro water and just a 2 part dutch fest nutes for my girls, altho i ended up having a cal/mag deficiency, was just wonder how to add cal/mag to the res along with the 2 part nutes.. because obviously when u add the cal/mag is raises the EC so you cant afford then to have as much other nutes. how do people go about this?
how to add cal/mag?

I would use 1-2.5 ml per gallon depending on strain. I would mix in cal/mag in RO water first, get tds/ec/ppm reading and then add nutes to get remaining level you want. In DWC RDWC you can run a lower EC/ppm and the plants will grow like crazy, just finding that sweet spot for each stage.
Rooted seedlings/clones - 125-250ppm
Vegetative - 250-700ppm
Flower - 700-1000ppm
Some plants can take more than others, just have to find that sweet spot.

Led grows require 5ml per gallon entire grow til week 7 for good healthy bud i also recommened compost for root protection like hydroguard.
