Do you need to add calmag(bottle) when using Jacks 321 to buffer the RO water or can you just increase part b(cal) and Epsom(mag)? I also noticed some PH issue with straight RO so im cutting it with Tap and got around 80ppm and I dont need to PH my water with Jacks 3.6/2.4/1.2. Ive been having magnesium deficiency with jacks321. Im also doing Drain to waste with coco coir/perlite 70/30 mix.
