Facts Behind Importance of Flushing

I just love these threads on flushing vs non flushing always get a laugh. I see all the posts and studies done on the ill effects of flushing on a plant and all the opinions put forth on flushing. Maybe if I grew hydro and was pumping my plants so full of shit they don't need I might change my mind. Growing in a good organic soil where my plants are able to uptake what they want and bypass what they don't want, why would I ruin good soil? Want to water your plants the last time without any additives great just like nature does with a rain.
Personally I will keep my plants happy until the day I chop, dry them and cure them properly and enjoy.
