quickly enough to the ever-
 changing circumstances here as the plants.>

Um, well, yes, plants do produce CO2 as a waste product when they
convert stored carbon into energy, but I meant the plants use
atmospheric CO2 to make other carbon containing compounds, like
proteins, carbohydrates, lignins, etc etc (i.e., organic matter!).  This
particular article didn't mention trace elements or other factors
affecting the plant's ability to fix carbon/photosynthesize/"grow", but
that's the point I was making.

Irises have the capacity to store energy as various carbon compounds in
the rhizome - I'm sure we've all seen rhizomes with no roots managing to
grow leaves.  However, eventually they need to take up water &
nutrients, including trace elements thru living, functional roots.  As I
remember, some of that uptake is passive and some is actively mediated
by enzymes & other junk both inside and outside the iris.

Lots of activity in root rhizospheres where fungi & bacteria are both
using carbon leaking out of plant roots for energy and providing other
compounds for the plant.  Another reason why antibiotics and fungicides
and other toxins (Clorox) might be counterproductive in the long
run......

Anyway, the more good health the plant has to start with, the more
energy it can put into repair, assuming it has the capability.

<And I expect different types of damage may require a  different
approach by the plant, resulting in the  variability of affected plants
that I'm seeing.>

Seems likely to me too.  Plus with all the genetic variability in modern
bearded irises, the way individual cultivars respond to a single type of
damage might vary a lot too, quantitatively if not qualtitatively..

< I guess a lot of my plants are allergic to my conditions :).  >

Your plants may not be allergic, but I sure would be if I tried to eat
them!  No veggies from Donald's, thank you! <g>  I guess this is why my
allergist recommends organic produce.
