I would keep it simple and just check the ec of the distilled water after adding cal mag. If the ph drops in the nute mix then I would add a little more cal mag next time (or just add a little more to the rez). Once you are dialed in then you can just mix it up without checking anything and your ph will be pretty stable. I run the 3 part GH at 1 1 1 the first few weeks then switch to Lucas Formula. Now I have gravitated to FloraNova and use the Floranova grow through the first couple weeks of flower before switching to Floranova bloom. I get less leaf fade this way.
