You know, I've done it both ways. What I've found is this. You can adjust the water prior to nute addition. Adding the nutes is gonna change the ph and then you have to readjust after addition. Making the first adjustment therefore was a waste of ph up/down. Soooo, I just add the nutes to the water, let it sit and bubble for a while then adjust to where you want it. I use calmag in my res at the rate of 2ml/gal when using plain tap water(usually 7.2-7.3 here) and 4 ml/gal when using RO water. I do notice my ph drifts more when I use just RO water more so than when using plain tap water. Just my take on ph adjustments. RR
Tip for using Clearx, I use it once a month during the growth cycle mixed at 15ml/gal water. As it floods the table(usually for about a hour, or until EC/PPM settle out) about every 15 minutes I scoop some up in a container and pour over the top of my rockwool cubes and lightly "rub" off any salts residue.Just seems to clean it up a bit better allowing better air exchange. At the end of the bloom cycle when I begin the final flush I mix at 30ml/gal water and do the same way as stated above. Flush until ec/ppm settles out then pour out that water and add fresh water and a product name "Final Flush"(unscented) and let it run on your normal feed cycle for 2 days.I then replace that with plain water for another 4-5 days changing the plain water daily. I have found that doing it this way really increases the flavor factor and removes any chemical elements. I know that was a lot off topic(lol) just tryin to help.
