PH drift

hey all i have a quick question. how fast does your PH drift? mine drift from 5.8 up to about 6.2 or 6.3 over a 12 hour period, is that normal? i am in the process of switching over from soil to hydro, but i have one DWC that stays stable and drifts about 2 points over a few days, but that one goes up over a 12 hour period is making me think it has a unseen problem. also will myco madness cause the PH to stabilize? thanks for the reply's up front ya'll

what type ph- you use?

Depends on how fast your plants are taking up nutrients, rapid pH flux can also indicate rootzone disease. Some pH drift is a good thing because different nutrients are absorbed better at specific pH ranges. Smaller reservoirs will generally require more pH maintenance as well. Without more info I can't say definitey but your pH range sounds healthy

Are you noticing your PPM's go lower and pH go up? If so that is a good sign that your plants are doing well and eating well. Also did you soak your hydroton in pH'd water after rinsing them? I noticed if you don't you'll get pH drift for a little while then it normalizes.
