ok for a start removing carbon dioxide from water by using an air pump will increase the ph. so by actively aerating with an air pump and an air stone you are removing carbon dioxide thus raising ph. so the bucket is not raising ph but the air you pump in it is. i’m not a hydro guy but updrifting ph is normal in an hydro setup and you should just bring it back as it drifts upwards. as far as i know i can say it is also a good thing that it drifts upwards than downwards. because that means your plant also uptakes some of the acidic nutrient molecules from the solution as well. keep adjusting as it drifts up and bigger the reservoir more stable the ph will be is a trick i learned from some hydro masters so in a small dwc bucket its normal imho.

It is a ph problem. Needs to be set at 5.8 through veg. 6.2 and 6.3 for flower. Cheers
