When to start the pre-harvest flush?

[puffdatchronic]

And that removes what from the plant cells? Soil itself is made of nutrients essential to life how are you stopping that from being absorbed, and where does the flushing solution fit into this?
. A deficient leave turns yellow because its recycling mobile nutes from vegetative organs to reproductive organs. There is no washing them away or using them up, even yellow leaves hold mineral content, think compost.

so ,are you saying that 2 clones side by side.. one nuked with nutrients, clawed, dark green , burnt tips ..and one fed sparingly and allowed to use up its own stored nutrients both chopped an dried ..side by side in the same conditions, would taste and smoke exactly the same?

I think some common sense in growing would be handy in this debate. Why would an unhealthy plant ever compare to a healthy plant in any way shape or form??
I think people who believe in this flushing nonsense encourage bad growing practices by telling people to feed a 5000 ppm because they can wash it all out in the end. Do you dark green clawed up leaves just heal themselves with some extra water?

Like I said plants don't "use up" anything its all used to build the plant. Some mobile nutes can be moved from leave to flower when deficient thats why the leaves turn yellow.
You cant force feed yourself 30 big macs everyday and think drinking a glass of water before bed is gonna fix it. Cannabis can absorb and store more metals than it could ever "use up" think about that when your feeding your plants because it doesn't just go away.

this is the funny part... so i guess a majority of people who flush do it because of quote #1 otherwise biophysically is quote #2 also not wrong when you thiink about it... so the yellowing gives the grower just some kinda feeling hes getting rid of those unwanted "chemical fertz" etc. and just smoking the "good" stuff [at this point if you smoke it you shouldn't worry about those ppm what gets in your lungs anyway, smoke is smoke]

so this is the paradox what i don't get and try to find out...

See if you can find anything reputable about "flushing" any other crop on earth. If you want to see for yourself how full of shit theses nute companies are google the ingredients of AN's magic flushing sauce " flawless finish" Its nothing but magnesium sulfate or epsom salt.
Most growers have an over feeding problem not a flushing problem. For some reason people think more is better, when in reality its just the opposite. They're like bulimics binging & purging plants.

common sense? you didnt give me a straight answer there.

using your rational an overfed plant will smoke and taste the same as a flushed one.

if you say flushing does not alter anything positively 'because nutrients dont work like that' then it shouldnt matter if the plant was overfed either.

I've flushed, not flushed I HAVE SEEN the exact strain grown the exact same way have sparkles when u smoke it and the flushed didn't. I usually wait til I know the plants done and flush with ice water the last 48 hrs it personally has brought out the purple in only strains that tend to have purple it brings it out more but same shit different flies. it isn't necessary. You learn to slap her around a little bit to get what you want. Like amping the heat in your grow up to around 90 last 24hrs and let the plant get a little thirsty and it'll push more sticky. Or go with cold and go for pretty.

Don't over feed. If you are buying nutes, start with 1/4 of what they say to use. Adjust from there. Weed nute companies charge two or three prices. No need to increase their profit by over feeding.

My general rule of thumb for feeding during flower.

1st 3 weeks, veg food
2nd 3 weeks 50/50 veg/bloom
last 3 weeks bloom food

Go get a nitrogen test kit from an agri center and then you can see how overfed your weed is. The same way farmers do it. Then with the help of mathematics you'll know how long you need to feed straight water aka flush.

PS most internet grower prefer high nitrogen pot, its the only way they can get faded off their shit, by poisoning themselves.

Less is more.
