I completely agree, I was talking about pre harvest flushing. Flushing to prevent lockout is a different story.Unless you are using synthetic nutrients and get into a situation where you have a salt lockout and your plants are dying... then, flushing is for those who wish to save their plants.
Flushing at the very end, to somehow clear the plants of something, has been debunked. That flushing at the end of the job, is indeed for toilets. Several nutrient lines however, recommend regular flushes to clear out excess nutes and salts... it is a thing, and they wouldn't recommend such a thing, if it were not for a good reason.
