So I've got this greenhouse.
I've spent a ton of money on top tier compost, EWC's, mostly 'Down to Earth Amendments to old recycled Pro-Mixes. Now with the help of this thread Fermented Plant Extracts and 'Keep it Simple' tea maker. Foliar Sprays of assorted sprouted, aloed, Ful-proed, obsessive compulsive disordered behavior since my other life is on hold until this crop is in kind of madness...
This is also documented over in the Side to side experiments of 'Regular pots/ cups vs Airpots" thread.
The plant(s) involved are cuttings of a Sour Bubble I started Last January.
About 2 weeks ago there was a lower branch that kind of 'faded out' and I thought maybe its just following course and a bottom branch had died.
Then This:

I dealt with root pith when some were small but culling took care of that.
The plant was culled and an inspection of the soil showed roots intact, seemingly strong no sign of rot or softness of roots. Top root bed about 4 inches with associated companion plants consisting of an array of aromatic herbs. Dill, garlic, rosemary, basil. None of these being affected.
My question for this group is about recycling this soil. My understanding is that pith is tough to get rid of.
Any thought out there about this...
watering was done via Blumat in an enclosed 50 gallon tree pot.
All plants are in individual 65gal smartpots or very large pieced together airpots at about 65 gal. None of the other plants are showing any sign of weakness.
Are you sure you mean pith?
Pith is the soft stuff inside the stems and roots:
Botany. The soft, spongelike, central cylinder of the stems of most flowering plants, composed mainly of parenchyma.
You sure it was a root disease? I've seen plants that have done that when girdled, often unintentionally, for example, you set up a bamboo cane and a bit of string, that ends up being way too tight when the plant is 4 foot taller.
If it was a fungus, silica clays are an excellent defense, sprinkle around the base of your plants.
