One is based on evidence and one is based on anecdote... the score is about 1,855,342,342 to 43, evidence to anecdote, lol. First, let's assume basic competency and not some dumpster fire of a plant with a plethora is nutrient imbalances. Flower is a sex organ. It does not store excess minerals. This is why when they test flushed and non-flushed flower, there is no difference in mineral content. The flower is made of the same stuff, regardless of flushing. Molecularly, it is not impacted by flushing, unless a deprivation is caused then you get less, because law of conservation of mass -- you can't just make mass from nothing.. the atoms have to be there. cell differentiation. Various tissues perform various tasks. flower is for sexual reproduction. Not a whole lot of photosynthesis or other things are going on there. Do your balls or ovules store fat? No, because that would be absurd to think various bits of anatomy are a jack of all trade Go ahead and do it, if you want. Nothing too wrong with it as long as the plant isn't deprived of necessary building blocks. If it can cannibalize itself sufficiently, nothing is lost. This also depends exactly how the building blocks get where they are needed -- does it cost more energy to move stuff out of 'storage' or is that already part of the pathway, regardless of from the roots or from 'storage'. This is probably a question that is already figuerd out and could look it up. If it costs more energy in any way to cannibalize itself, that would result in 'some' loss due to less efficient use of ATP and less of it being avaialble to produce tch and terpenes etc that happen to be 'uphill' reactions. The red flag is that the reasons they give as to why keep changing as they get proven wrong. It's like playing whack-a-mole. oh, it's this! nope. Oh, then it's this! nope. LOL at some point you have to recognize when top-down (inductive) reasoning leads to obvious errors.

Let’s address these anti-flushing arguments one by one. Flushing your plants does not involve robbing them of nutrients. On the contrary, flushing allows your plants the chance to use the excess nutrients they have accumulated throughout the grow cycle. When you feed your crops full nutrient loads right up until the time of harvest, they retain an overabundance of compounds that affect the quality of the final product — including its taste, smell and overall smoothness.It’s also important to note that the main purpose behind flushing plants is not to encourage substantial new growth — although, flushing can cause your crop’s floral blooms to swell, since plants are not expelling all their energy on nutrient uptake. Any grower who has experienced nutrient burn knows the argument that plants cannot expel excess nutrients holds no weight. Ask any seasoned cultivator how to fix nutrient burn and they will tell you: You need to flush your plants and allow them time to use up the excess nutrients.The same logic applies to pre-harvest flushing. You’re giving your plants just enough time to use up surplus nutrients, salts and other compounds. The argument that soil can’t be effectively flushed is simply illogical and just plain wrong. Plants grown in soil can be flushed — it just takes a longer period of time than flushing plants grown in hydro or coco. It’s true that withholding nutrients places stress on plants and causes them to increase defense compounds. However, in certain plants, the primary defense compounds are actually the most desirable constituents, so flushing before harvest can significantly increase the value of the final product.

flushing is a tool, not a step...if you want more information you can find it... otherwise folks are on here weekly regurgitating the same crap are you wanting a sassy fade? is your medium a nasty one? have you overfeed? is your cure and or dry set up for rapid turn around of clean dank zaza and you want a small time boost on getting to the finish line? is your nute line garb? I flush regularly. In hydro. This makes the turnaround on the system clean better for me... It makes the fade hit predictably (which helps when I know a cut, not when I don't). It makes my cure take 2 weeks and then it is great. If I press any rosin I get a better oil... Anecdotally, I have never skipped anything by flushing that couldn't be fixed by the 'old timer' 3 month forget about your harvest / sleep dope cure.... I'm an extreme flavor chaser, and I can't stand trash flower.... I'm literally chasing single digit percents of free salts... Flushing is on the same order of benefit as harvesting at night. Technically it is correct. If it is done in isolation it will have a nominal effect. If it is done in sequence with a dozen other things all aiming for the tastiest and cleanest flower, then you will cumulatively see the difference in product.

It's contravertal, some feed upto the end and you would with coco but me with soil like to give only water the last week to clear out the medium for its next use and I also think the smoke is less harsh doing it this way but that's just my opinion..

Flush your shit not your plants. Flushing is a tool to correct a catastrophic issue in the medium/substrate. Not a tool for end of life harvest. Just giving water end of grow is fine and is not flushing. Flushing agents are also bunk and waste of money.
