I have always grown in soil and have never flushed. Using organic soil and nutes, I don't believe it necessary. That being said, I have a friend who uses a non-organic nute and he flushes but his weed always taste like dirt or worse. Mine always taste good with subtle differences in strains easily noted...

I agree and disagree.
That is, plants actually don't absorb "organic chemicals", either. They mostly absorb inorganic ions (ions carry a charge, + or -), which may or may not have been derived from organic compounds. Whether the ions were derived from organic compounds doesn't really matter to the plant (but it certainly matters to the soil).
However, there are synthetic chelating agents to consider, which are prevalent in hydroponics fertilizer. EDTA for instance is synthesized from ethylenediamine, formaldehyde and sodium cyanide (nasty precursors) and forms complexes/salts with minerals (like iron) making them more soluble and forcing their absorption by plant roots. The big question is whether the EDTA is actually absorbed by the plant, and whether it remains in plant tissues after harvesting. Some studies have demonstrated that most of the EDTA remains in the substrate; it releases its mineral counterpart and then it can go form another complex. Other research has found some EDTA in plant tissues.
Either way it isn't great. EDTA likes heavy metals (mercury, lead) and can shuttle those into plant roots as well. So if EDTA released its metal to the plant and then was free to join another complex, it would prefer to do so with a heavy metal. Absorption of other elements like aluminum can be influence by certain factors also, and even minerals that are required by the plant are much less 'safe'/'unhealthy' when present in abundance.

lol, so your saying growers who use synthetic ferts have weed that tastes like dirt, LOL, thats how that sounds

lol, old guy fertilizer complex, he uses shit for his grows and finds "subtle differences in taste". My dad's cows eat alfalfa and his neighbor feeds his field hay, there's your subtle difference buddy

No...my only input comes from what I grow and vape, others feedback on my buds....and comparing to 2 friends who have dank weed but taste like dirt.....they use synthetic...we first thought they weren't curing properly ........so my input is small but very useful to ME.....LOL....I'm about to go vape some of my organically grown buds and savor all it has to offer.....

haha i wish i could get a solid answer on this topic....couldn't it theoretically hurt yield if you stop feeding the plants for the last 2 weeks?

I grow organically, and depend on molasses as a chelating agent. Flushing risks bud rot, and is not usually necessary, according to growers far wiser than me. The thought of all the nightmares I've read about bud mold, after so much time and trouble invested, is not worth the risk as far as I'm concerned.
Mandala Seeds has a good page on the pros and cons of flushing.
