I used to swing mine but this time just did a solid 5.8 & 6.0. Both hit in the middle of the range so allows for the pH meter to drift slightly & still be in range (which it will do by 0.1 after a couple of weeks).
Probably nothing in it, seems seedlings like a slightly lower pH. Probably not much point swinging it about, but as long as it’s in the range technically then it’s “correct.”
I find shooting for a set number makes mixing easier. PH down to 6.0, come back 15 minutes later & see its drifted up to 6.3, pH back down to 6.0 & repeat a couple more times until it’s stable @ 6.0 so I know I can water the plants without the pH drifting in the coco.
Are you checking this every day? It’s likely the pH will drift over a few days & should have a pump or airstone in it to keep it mixed, oxygenated & the pH stable. If it does drift (it’ll probably rise) shoot for the lower end of the spectrum (say 5.7) so as it rises it’s still within range.
I ran my E.C up to 1.5 but that was using bottled water with a background EC of 0.1, so you can run a higher EC without all the shit from the tap water in it.
I think it’s widely agreed upon that adding more nutes (while tempting as you think the plant will grow more) stresses them & you’ll struggle to get all the nutes out come flush time so will effect the quality of the smoke.
If you up the EC too high in a hydro system you’ll see the EC of the reservoir shoot up as the plant says “fuck nutes” & just drinks water, where the EC should stay consistent if it’s at the correct level for what the plant requires s they’ll drink both in equal measures. But you don’t see that with coco, so you can easily keep over feeding them (admittedly you could test your run off, but you wont have issues as ling as you water with plenty of run off, keep your meters calibrated & don’t overfeed).
I would’t fixate on a number, just look at the colour of the plans & feed them accordingly. If they’re underfed up the EC by 0.1 & asses again in a few days. If they look overfed back off & so forth.
I think a lot of it comes down to experimenting to see what works best & with what strain. I am doing Gorilla Zkittles next & hopefully it ticks all the boxes so I plan on doing a few runs of it to really dial it in.
