That's what I don't buy from him. I'm sure it applies with their soil mixes but you cant generalize every pot mix and different kinds of waters/mix like that.

It's the contents of the water that will cause it to drift over time.
Make sense to me....
His last answer should be "Yes, depending on the dkh of the water you have been using over time".
Adjusting the ph of the water will slightly adjust dkh. Moreso if your raising it.
Effects of dkh of water are covered pretty well in the saltwater aquarium hobby.
I try to think of it (dkh or carbonate hardness) as the 'ability of the solution to stay at that ph'. It's like ph is a derivative of carbonate hardness.
I don't test for dkh of my nute solution. I know the dkh of my cistern water, maybe I should test it after applying nutes to see it's change, but considering most of the nutes I use lower ph, the effect on the solutions dkh is negligible. I would imagine it to be pretty low, considering how easy it is to adjust the nute solution.
When one goes to carefully 'adjust' the ph of solutions containing higher carbonate hardness it is a little more tricky than just adding some drops to the water.
For most of us, this will be a static factor that we really don't think about as it's not really varying in our daily nute prep. Should growers target dkh? Hell no. Should growers know if they have a hardness issue with their water? YES. Hardness is alkalinity.
Your showing your age when the question was not answered. I only say that because I am there too.
The issues in soil with dkh would be a buildup where nutes could not stay in solution in the soil. Farmers know this (we have crop rotation for this issue and others). So, the evil type 2 error occurs when someone is unknowingly giving hard water nutes over time and they get lockout even though their ph'ed water is right all the time. It happens, your on a well, and/or you have excessive co2 in water.
Hard water where grower A lives is not going to be the same as hard water where grower B lives.
Cool conversation.
You don't have to buy it. He's stating scientific facts for soil and soil-less media. Not for ProMix specifically.That's what I don't buy from him. I'm sure it applies with their soil mixes but you cant generalize every pot mix and different kinds of waters/mix like that.
The content of the water determines how the roots respond. This is what he's saying in 2 a-d.Plus the action of the plant - it’s a combined thing. And the action of the plant is affected by what’s in the water too.
I didn't really think you meant it as a diss.I was experiencing no judgment about either in my thoughts so I’m sorry if it came off like that!

Ok! But what do you mean by “you say that like it’s a bad thing” and also what what you said about not turning it into a battle of the grow method? Maybe I’ll just go back to bed... I thought this was an interesting discussion. I wasn’t battle mongeringI didn't really think you meant it as a diss.
ProMix
I didn't think you specifically were battle mongering. I didn't mean to be ascribing that to you. I was hoping my exclamation mark indicated that but it may have been too subtle.I wasn’t battle mongering
This is soil science Crazy, not some paid shill. He sent me links to university studies and farm research that has nothing to do with ProMix. He wasn't even talking specifically about ProMix. You don't need to believe it and I'm not trying to convince you. I am letting you know that his knowledge on this subject runs much deeper and wider than yours, mine, or anyone else I know of here.But they pay his study?

This is not what his science says. It says that the type of nitrogen in your fertilizer will determine whether your pH rises or falls, along with the raising tendency of high alkaline water.Continued application of low-pH nutrients will reduce the effectiveness of the lime over time.

I was just talking about this:Absolutely the type of nitrogen is involved! What I wrote was shorthand for “solutions which induce a low-pH-condition”.
It's not low pH nutrients, it's specific types of nutrients that will make plants release of hydrogen ions or exchange hydroxyl ions that then changes the pH of the substrate.Continued application of low-pH nutrients will reduce the effectiveness
words on pages can suck sometimes but only briefly,indicated that but it may have been too subtle.
I wish you did tooWish I had the room for science.

Perfect So I’m suggesting that what you want, then, is a nute line that works to engage the plant in all the right ways for using the particular chemical balance said nute line provides in soil.it's specific types of nutrients that will make plants release of hydrogen ions or exchange hydroxyl ions that then changes the pH of the substrate.
I think it would be difficult to formulate given the variation in water alkalinity, as well as differences in substrates when they are making nutes for coco/hydro/soil/soil-less. I mean MegaCrop can't even figure out which NPK formula they want to go with (three different ratios over the last three months!).words on pages can suck sometimes but only briefly,

Do any nutrient companies claim to do anything like this? :curious:
