i think either does the job if am honest mate as i have done none ph'ed many moons ago without issue but took few days get ph settled in root zone. i like idea that say for example am ph'in at 5.8 in veg an i need flush for X reason , i flush at 5.8 so then i can bung a 5.8 feed in straight away an theres no issues with ph gona be out. same for flower i do i mid flower one to freshin up the coco as i find they love that shit so i flush at 6.0 ish.
its just what ever work for you mate init. not sure on ppm as i measure EC, i stopped using my EC meter most time tbh an just go off how plants look. it is handy though to check run off ec every now an then see how plant is feedin
