I'm glad to hear the way I do it recommended by you. Lol. Know I'm doing it right then. Lol. A question to the above post as well as I'm curious, and your smarter than I. Might answer some questions for OP as well.
So if I understand it, a living soil should self regulate it's ph over time. But can't it still change quite a bit either from top dresses, and or other ingredients involved from prior amending? IE: I had soil of a 6.5 ph before needing to topdress some various bone meals and bird poop for a P increase for hungry plants. Had to avoid any K inputs. Already had a bit of K burn from a bad decision i made that they were recovering from. 3 to 4 weeks go on, they got better, P def left, K burn mostly subsided and then worse, a lot of micro defs and Ca especially. Checked ph and it had climbed to a bit over 7. I've had this happen in an outdoor grow awhile back, the ph rise from amendments. This was my solution then with no ill effects so tried it again now. I did a elemental sulfur watering at the following ratio. A half cup/gallon into hot water, really hot water, power mixed with drill and paddle, let cool, mixed again. A total 3.5 gallons mixed. Watered all 9 plants well, a bit of runoff from each, equal distribution to each. 24 hrs now, ph down to the 6.5ish range, a couple closer to the 6.2 range. Plants dramatically happier already. Would the soil in either situation have eventually resolved itself and gone back down had I given it a lot more time? Or is it also possible that the mostly peat based soil I have, recycled 4 yrs now, has lost its acidity? Similar to what you had happen I've read in your thread? So then did the liming just take over? Eventually will the bacteria or liming counteract the acidity of the sulfur I've added or further break it down adding to the ph drop? Or did i just speed up the equilibrium of the whole thing? Curious about all that. Ill test soil ph again tomorrow and update any changes. Here's a 2 days ago and a today pic for comparison.
