I guess what gets me is that many times I read your diagnosis to a problem or explanation, and shake my head. You say that I have no personal experience but why do you draw this conclusion? You know nothing about me. Or I guess what you're trying to say is that you always think I'm wrong. If that's the case, then I have a question for you.

Why do you focus so much on pH and rootbound/rootrot when the starter of the thread hasn't given any mention that could indicate these conditions might exist? . Your explanation for every spot, every bent leaf, is usually one or more of those three things.

Your ruler analogy is correct, to a point. The accuracy is dependent mostly on how well the measuring device is used. (But I see what you're saying).
Datum is singular for data.
"Especially if one has a habit of doing heaping measurements 3 times a week rather than one level measurement, once a week."
I understand the percentages of smaller amounts, but I thought the above statement was strange. The starter of this thread stated he was only using Plagron soil, without adding ferts. There was no habit developed yet.
"If you don't lower the quantity of nutrients per application, you'll kill the plants."
My text says water, not nutes - 3 times the normal amount of water given three times a week doesn't strike me as smart. But I'm sure you'll just say that's another indication as to how stupid I am.
"All you want to do is try and fight and find fault."
Not true. This is the first time I've said anything of this nature. You have told others in the past that they're just guessing, but you are the greatest guesser here, in my opinion. Rusty has told people in these forums that there is no difference between organic and sythetic (chemical) fertilizer. This is not accurate. Organics are heavily based on carbon. Sythetics are made in a lab, low in carbon, and designed for rapid utilization by a cellular system. Organic ferts take longer to be utilized and require the presence of bacteria (in most cases) to break the fert down to a molecular level that can be absorbed by a plant. What people don't understand is anyone attacking a senior member. Period. I'm sorry but RT doesn't gain my respect. Not like he does from the rest of you anyway. I have yet to be impressed by RT and his "datum."
"likely I'll be here helping other med patients"
You can have it, but most aren't med patients.
