Just played around it and yes it is.

Citric can take a while to neutralize the buffer in the water and the pH can float around for a couple days.
Phosphoric will stratify with a low pH layer at the top after stirred once. It needs to be mixed in several times before ready.

I found citric acid fleeting when I was phing water for some Blumats. 6 one day, 9 the next. The smell was nice though.

The pot I am playing with has been 2.4 for two days now.

I alternate between citric acid and phosphoric acid as a PH down. . My water usually comes out in the high 7s-low 8s. I’m running organic soil so my dirt can tolerate that for a while but I want to avoid any buildups. So I don’t balance every single time but I do it most of the time, and I don’t want to just keep adding phosphorous, and there’s evidence that the citric acid can even aid in helping my in-pot composters break stuff down so that’s nice.
