@Gman753 please don’t cross post the same issue. Once is enough. 😁👍 Temps can cause pH fluctuations and pH adjusters only last so long. I think you need to check and adjust more frequently to 5.8 pH. What are your water temps? ---

That’s the end of my dwc knowledge! There are lots here using dwc. If no one chimes in I will tag some folks. That’s one of the downsides of water growing. How many gallon res are you running? Are your plants sharing the same res? ---

@Gman753, there is a product that is supposed to stabilize ph over time that someone here referenced. The name escapes me but failing that you will have to monitor daily. We’ve had a number of members get bit by cheap out of cal ph meters so do check calibration frequently. My experience with GH Grow is if the ph of the parent water is neutral or close to it, the nutes drop it right in to 5.8. As I’m doing coco and don’t hold onto it I don’t know how long it remains buffered. ---

Thanks @bob31 I’m no expert but I did have problems Keeping PH stable in my res with an air pump running. If you need the air pump the you will have to adjust ph more often as it def makes it rise. ---

my experience is limited, I’m on my second DWC grow…it’s very normal to have the pH rise after a change of the reservoir and fresh nutrients are added as the plant eats…you may find the pH fluctuation less severe when you start feeding the plant higher ppm’s as she grows bigger…it should stabilize in a few days with your adjustments after the res change.
