UPDATE:
This is working. In the room with an attempting outbreak, There is no further spread and all previously treated area's on plants (green cure) post sulfur burning. Have had NO returning growth.
I find it as significant that on the lower area's of the plant (usually where anything that escapes a burn) have not shown any starting infections. Usually I would have to come around and treat lower area outbreaks with GC after solid, long burns.
I am going to forgo a new sanitizing till after the room is harvested. Just to see how this increased RH does. I suspect it is going to hold it in check, completely..
A noticed bonus - Reduced feeding solution amounts per pot - no matter the size. The no matter part, clearly indicates an overall better use of feed/watering solutions. Oh boy, lower production costs!
This could call for a redo of gassing to recalculate the returns vs cost.... be close but maybe worth the try.
Overall great day. Well, except for the fact that the Texans could not allow my beloved Spartans to give me a BD gift......Well, we made it back to the final 4. That still worked...

I think that I understand what is happening.
This has to do with plant cuticle correct?
Here's something else interesting,
https://www.jstor.org/stable/2444899?seq=1#page_scan_tab_contents
I'm trying to find it in ebsco academic search complete.

Sorry to say these are not it..This wax layer is a separate thing.....The pictures in the article are electron microscope shots of the layer surrounding and including a stoma., a healthy one.
BUT, Nice on the second one as far as interesting info on Terp and THC accumulation and formation area's! Quite interesting really.
I will mention that trich "covers" are a form of a wax and ester compound.....Again, part of what you remove with wintering our extract and filtering.

It consists of lipid and hydrocarbon polymers impregnated with wax, and is synthesized exclusively by the epidermal cells.
There is another separate wax layer from the cuticle?

Interesting find.

Once I grow up and get smart. I'll read more then an abstract....And half a page..
Once I went back and read the whole thing... You ARE correct......Yes, that layer..
Like I said though, very interesting on the Terp and THC in that paper.....

The implications are far reaching. I'm looking for more information.

Kinda makes you think that high N - limiting trich and THC production. Might be from "blocking", by an over abundance of the wax being formed and clogging of those secretory cells...

I just read something about humidity and the relationship between stomata, the thickness of the cuticle, and transpiration rate. I want to go back and read it again, but I have to look for it later.

Heya doc, I was workung at a hemp farm for awhile...the rh in the indoor grow was equal to a rainforest. I was bent about this but out of my control. I gave the plants a nice n feed and the next day came in to find shiney leaves. Went from dull to shiney.
Also found out hemp farmers dont sulfer burn..they use sulfer powder in a water mix and spray. I got to reading about sulfer and was pleasantly surprised that most farmers use sulfer powder and how good sulfer is for us. Etc.
My 1st application of sulfer I had a guy apply it with specific instructions and i go to check on him and hes saturating tf outta the plant. Caused the plant to have cloudy residue all over the leaves, i did not approve so i washed it all off..the following week i applied it myself and sprayed upward motion to get just the underside of the leaves and also used half of recommended dose of sulfer.

That is quite right!
Hemp is a sativa and from sub tropical area's around the globe. I find better growth with higher RH and landrace Sativa's.
Outdoors on the farm S in water is employed.
Indoors in a greenhouse at my dates of experience. It was mainly a burn and then open the vents.
S is so important to plant growth. It is debated regularly by scholars and the DOA about actually making it a macro nutrient to amend the NPK to NPKS. I don't really understand those opposing it. It is so important.... With out it, all plant life fails and many of the other nutrients are not absorbed/available - making another point.
In what we're doing here. I have to now retest some different strains for any reductions in terps/THC from increase in the cuticle layer....Being prudent with N is going to be more critical here I would think....

Not knowing how you grow, how will you manage the what I will call "transferred transpiration" you say is happening?
You said the increased rh reduced the feed uptake. This means more O2 is being produced while using less food. There must be a breaking point, to now with these plants perhaps there are stores of nutrient, but what about when the high rh is present from the beginning?

[high rh reduced waterfeed uptake]. higher rh=slower evaporation only time I got pm indoor was when rh was not controlled below 60 just saying.

There are many types of stomata - our our adapted to certain things why mj does well in certain areas. I have yet to see much on this and followed hemp stomata data.
I ran high humidity - leaf fingers got longer i.e. morphology change and i felt more waxy visually although i would need to recheck the wax part one day.
Interestingly if you start a seedling in high ferts then reduce to normal it will have gained resistance to futher high fert levels a little.
Why do i feel that theres somthing missing here

How much was the swing in rh tho?
Might the problem have been too low temp?
I am finding moisture capacity is a critical factor when considering the quality of environment. Control and stabilization of the environment come first, then we can worry about optimization. This is why I recirculate my exhaust air to precondition the intake air due to large difference in temp and rh of the two.

ya swing in rh wasn't much always high 60-70 but do deal with big temp swings.i have no problem now run dehuy 24-7 right at 50.i also run with a lung room gets to cold here to pull straight into room.
PM thrives in high RH but cannot survive actual contact with water. Best PM defense is to spray plant with clean water during veg. Rain kills PM. PM can live with any RH over 50% and no direct water contact. Until its really takes hold as soon as water hits PM it dead. Make it rain!
