It all depends on the plant food and what's in the mix. I could keep my DWC reservoir pH stable for weeks on ends running Dyna Gro with 50 gallons for 4 sites DWC.It will always rise, if that’s your input water. Ph Down is only temporary.
Ours pips up from 5.8 to 6.2 in a day, full flower we’re Ph’ing the tank twice day before each feed. @Wastei probably someone that can give more info as did DWC for a long time.
I’ve looked at getting a BlueLab adjuster but its $600 so I need to sneak it in when & Co is in a good mood
That and other similar ones only have one mode. You can choose up or down. In our case and it seems yours we’d choose the “Down” mode. You hook up the dripper to the reservoir and when the sensor placed inside see’s it go 5.9 it drips a little from the Ph Down bottle its connected to. Others with different water or usage might want Ph Up though I reckon that’s far rarer.
Have looksee on AliExpress - there are some decent looking Chinese made ones as well.
But I’m pretty comfortable now with a bit of Ph play. I’ll let it go a little up or a little down, your slightly changing the macro and micro nutrient uptake to the plant. As they say a varied diet is the secret to a healthy life!

With traditional 2 part feed I pH adjust maybe two times the 2 first days before it settles. I set it at 5.5 and let it drift all the way up to 6.3 ideally. Then you get a good range of different mineral bioavailability throughout the day, pH up drift is good and normal in a healthy system. Use it to your advantage!
Running high dose silicate is your best friend for pH stability in water cultures, 30-50ppm residual Si really helps to buffer pH and slowing down the drift. That's max dosage for Dyna Gro Protekt containing potassium silicate.
Cheers!
) but as I think I said and you did its actually healthy.
