Why not mix them half and half. Then it should be around 7.
Ya, or just buy citric acid since that's all it is. I bought the Earth Juice crystals before I realized I could get it way cheaper. You can get a 5 lb bag for $18. It was actually cheaper before the COVID shit. I paid $14.49 in Feb.
Good to know, I'm almost out lol. Thank you
Fresh lemon juice is fine. That's basically citric acid.
My tap ranges from 70-150 but you can always call or email the guy over at kind soil and ask. He was very friendly
R/O water don't have buffers, so the Ph will change easily. I would stick with R/O water if you bought the filter already, your thinking about it too much. In organic soil, I don't like my Ph above 6.2 because of micronutrient lockout(recurring problem for me).
Vinegar too. However, don't use the stuff from Heinz because it is made from petroleum products. Apple cider vinegar/Brown rice vinegar is part of the KNF method and it's actually helpful to plants... Well, Heinz has a new "all natural" formula now, just watch out for the other stuff they make.
