Lemon Juice & Vinegars As PH Down?

[themda]

Well I don't usually pH my water. I let the soil buffer it for me. The only time I've used citric acid in my water was to help flush out some extra Ca to lower my soil pH. I usually just give plain water that's between 7.2-7.5. But occasionally I will feed some organic liquid nutes that lowers the pH to around 6.0, sometimes less.

It varies from location, the Nutes I use in veg don’t lower pH at all (my tap water pHs over 8.0) so I always add citric acid (not the powder for cooking, in the form of lemon juice). The Nutes I use in flower bring the pH down to 4.5ish, especially when I use molasses which is acidic as hell, and I have to bring it back up so I use baking soda

I've been using Apple Cider Vinegar (5% acidity) to pH down, but switching to Harris Pure Vinegar (30% acidity). Only $12 for 32oz.

I started using apple cider vinegar to break down the calcium carbonate in my hard tap water. That's the idea anyways, not entirely sure if it's working, the soils pH seems to rise to 7.2 every 4 weeks. Even with the pH of the water dropping to 6.5 (average) the soils pH rises to 7.2. I have been pouring in the Seabird Guano (20% Calcium) so that could be the thing raising the pH. The usual fix is ewc tea. So every 3 to 4 weeks of ewc tea might be the thing to do.
