Flushing is very stressful. This is a topic that gets discussed ad nauseum here. I used to flush too, and because I wasn't doing a great job of drying and curing, it seemed to improve my results. Once I learned to dry and cure better, I found that flushing was not needed and once I was able to keep a plant green all the way through harvest I could see that the results were even better. It was not easy on my ego to admit this, but the science becomes difficult to ignore the deeper you look at it.
A lot of folks have flushed forever and they won't try not flushing because they like their current results. I get that. But it is frustrating when they say it is the best method and they haven't tried not flushing. I can say I have tried many different finishing techniques and I do not see a need to flush at finishing if the plant is healthy.
