Hi dutchman. Ok, we get you, they clearly stated it's a fungus. I've asked at least once, if not more than once, based on what? There should be, and are, ways of telling whether or not the issue being discussed is indeed fungal pathogen in origin, or one of the nutrient issues that many of us, myself included, have witnessed that were finally determined to be nutrition-based and resolved via nutrient adjustment.
So, I ask again, these statements are based on what (observations)?
E.G. Someone posts a picture of a plant where most of the upper growth has interveinal necrosis, as well as spotting and necrosis on the leaf margins. I read that as a calcium deficiency, and I can explain exactly why.
Thanks!
Here is thier answer after sending them the pics from here and I will not comment any more:
"The root fungus is not too bad yet, as displayed by the leaves.
Hydrogen Peroxide is good for adding oxygen to the roots but no good for root fungus, as to kill the fungus, you would have to have such a high concentration of it that it would kill the roots.
I have brought a plant back from root fungus, and it was exceptionally bad, if you want to see that post which I did about 2 years ago, look for superbluehaze, as that was the handle I was using then, and I did post with pictures.
There are no organic fungicides suitable for root fungus that I know about. I used a chemical fungicide. You need to treat the plant as soon as possible.
As has been said, friendly fungi and bacteria will only be good as a preventative measure, though there are I believe predatory fungi that kill the bad fungi on the roots. I, however, was unable to buy them here.

and here is a product to kill root fungus that is totally organic:
