Got the same issue. I have a hunch this rise is from the plants eating away all the food.
Some days it's really does raise and others it sits steady at 6.2 ... my conclusion was the light hitting the water. But I do also feel it's not so much the plants drinking... but something taking place within the roots, like a hormone when producing growth.. maybe it give off a little toxin that raises the p.h.. or dead plant matter? Within the res.. who knows.. but we know it happens... it isn't alot for me to have to check my res everyday. Just so much that it glides through the scale nicely throughout the week. It's very manageable
