I'm afraid to ask... possible impact from late intense trimming?

Question
Several people have advised (1) not to trim after two weeks into flower, and (2) not to do too heavy a trim at one time. I had to do both (see below if you are interested in why): What is the possible/probable blow-back of a *very* heavy trim/pruning 4 weeks into flower?

Background
I've only done one indoor winter run before, and it had hot lights/high temps, low humidity, and exhaust and inside fans turned way up -- so there was no way PM could survive in that environment. It just never registered that all those factors where why, and my other (indoor) grows were spring/summer or summer/fall, which were also hot runs with low humidity, so of all the plagues I've experienced, PM was never on the radar. Being that I thought it was a non-issue, I really enjoyed letting my plants turn into lush full bushes of foliage, they looked so healthy and happy that way...

I'm now doing my first indoor winter grow (in Oregon) with all LED/COB lights, and I've had to do things like add CFLs just to keep the temps up into the low 70's. It totally caught me by surprise (I know... Duh!) but all three of my spaces got PM after flipping to 12/12. While I was cutting leaves and coming up with solutions, it spread. I ended out having to do some crazy drastic trimming to try and save the plants. I'm not even sure what I'll get from this run, but I have read (separate topic I suppose) that I can make hash from them, because the water process will wash away the PM, also that they can be washed after harvest... or just made into edibles...

Anyway, just wondering what to look out for now in relation to removing... probably more than half the foliage, 4 weeks into flower. Could the intense late trim/pruning stress the plant and cause it to hermie? Might the stress cause it to take longer to flower? Or will it just be "death by 1000 cuts"? Just looking for a heads up from those who have been there and back.

The plants could stall for a bit and fall behind in bud production.

Least thats what happened to me. But it was a sensitive strain. Some strains might not be affected at all...

Thanks for that. True enough... I have four different strains that were affected, so I might have four different responses. They vegged for about six weeks and are in 7 gallon pots, so they should have good root systems, perhaps that will give them a good base for recovering.

Agree with Gquebed. May not be too bad depending on the strain, I have done before and didn't have too much of an effect

When I got PM indoors, it was from a combo of bad stuff.

Low night temperatures, not enough nighttime airflow and leaving drainage in the drip trays, letting humidity spike when the temperatures drop at night.

Now I run a small space heater during the dark period to keep the room temps level and my dark period humidity now only goes up about 5-10%

I ended up chopping early because I didn't want it to spread.

There were a number of factors that contributed to my issues beyond what I mentioned. Some were similar to yours @innerG , some were different. I started this grow at the end of summer, and was pulling outside air in to cool down the outer room. The weather changed and the outside temps dropped and I did not account for the rise in humidity... I've really not been paying close enough attention to this grow. I think part of it was that I was so fixated on how cold my new DIY COB lights were running, that I was focused on raising the heat but not paying attention to the humidity. Basically I dropped the ball.

I ended out putting a dehumidifier in the room, I run it at night. That's keeping the overall humidity down, and the handful of small grow spaces in the room are responding. I also increased the amount of airflow during the dark hours. I think things are under control, luckily I'm over-shooting on my grows and generally have more than I need for my patient, so if I get even half the crop, that will get me through to the end of next run.
