The effect of a Flush on Yield, whos got a yield protecting flush method??

My flush has always been the same... Coming into week 7 of flower bring the nutes down to a 3rd strength for one or two feeds then just straight PHd water and then a flush in the last week with a leaching agent (Growtek final flush) Before leaving to dry for harvest. I do it this way to try and reduce a negative impact on my final yield these last two weeks where as most people notice a lot of the final weight and density is put on. I was wondering the way other people do it to try and maximise yield? I think no nutrients at all for the last 2 weeks or longer is not good for yield but thats just how i see things... It may be a smoother smoke I dont know but im interested in yield here, ofcourse the bud still has to be to a high standard tho! Anyone got a method they would like to share other than the standard 2 week, no nutrients flush? Finally im aware not everyone flushes their weed but i do so i dont want to hear "you shouldnt flush" because i will anyway haha

Too much information running through my brain. That's in a dong by the police. Stewart copeland is the man

simple, don't flush..
