Well said. i 100% agree.
I do not 100% disagree with what diaz is saying either. A lil phing is not going to hurt anything but its not needed. Common sense says that he is right but the real world shows it really dont matter. You are not going to change the ph of the medium with just ph'ed water in a couple months. sometimes it takes years.
Thinking I need to is going to waste my time money and effort, possibly potassium and nitrogen pH will cause mineral problems, some raise ppm too much changing it.

I wasn't just saying because it's true but to help stop new growers thinking they need the next bluelab probe and pH kit or even bluelab thinking you can read soil and it's potential with a probe meter.

Well hopefully this info catches on quick! When i was saying this back in 2008/9 on this forum , i was getting yelled at like girls. nobody had a clue how them meters work.

What are you guys paying for the FFOF?

I buy local and the price is $14.37 out the door for a 1.5 cubic feet bag. 1.5 cubic feet fill four 3 gallon plastic pots.

How is PH'ing your water going to cause mineral problems?
What PH products raise the PPM's too much? You have to use a lot of PH up and down for it to matter.

I currently grow in coco/perlite, so ph is more important than in soil, but honestly I don't correct my ph even in coco these days, simply because I use RO water and know that my nute mix comes out to an acceptable ph range. I do test my res every now and again, just to make sure I'm on target, but I'm certainly not religious about it. I don't even use ph up or down TBH. I simply balance my ph with complimentary levels of Si and acidic organic based nutes.

That said, I did grow in soil for a long time before coco, and I for a long time just used tap water. One year I moved to a new place, and was growing in organic soil with non-ph'd tap water, My grow suddenly suffered, and I didn't initially understand why. I talked to my grow buddy about it, who grew hydro at the time, and he asked me what my ph was, and of course I told him that I grew in soil, so my water ph didn't matter. We debated it for a while, and a week later I decided that I might as well get some ph strips and test my water. Well, I came to find out that the water was ph 8.5. Wondering if my buddy was right, I got some ph down, and corrected my water to 6.5 for the next week or two, and the growth difference was night and day. This is my real world experience, take it or leave it.

If your adding a potent base like potassium hydroxide that's basically lye on your soil everytime. It is because of reports of this building up that we avoid doing so.

Irrelevant, your trying to cover the backs of those who do something that pointless and make too much talk about it.

I've never heard of people getting a buildup from using PH up. Seems like you would have to use a lot of it.

About as much as is in a slight over dose of potassium which could occur in a few waterings at 150ppm on top of fertilizer.

Not a lot past your fertilizer as the potassium in 600ppm fertilizer might not be much over a 100ppm as an example I just made up with no real bearing.
