Need some advice on flushing last weeks of bloom

What is the "correct" way of flushing plants before cutting. I usually just give water with a powdered nutrient called Dense and the ppms are 3000+ the last two weeks. Yet I know a flush should have little to no ppms. Any advice? Don't be afraid to tell me I'm doing this completely wrong.
You're doing it completely wrong. You feed slightly reduced ppm nutrients towards the end of flower. All the way until harvest day then you chop the plant down. No reason to try to make things complicated.

do i melt the snickers down or stick it in the dirt
Listen, I'm not going to give away all the secrets, but I'll help you out here. First, research "spikes" as your background. Next, FREEZE the Snickers bar. That was just an example, different strains benefit from different candy bars. Snickers is fairly neutral with the exception of the chemdogg family which is allergic to tree nuts. Frozen butterfingers, Charleston Chews, twix, to name a few.

So turn off your blurple at least 48 hours before chop. During your flush, spike the frozen candy bar into the soil. Don't worry about the roots, they like it rough. The frozen candy bar ALSO reduces the temperature of the root bed.

You're welcome.

From a leaching point of view @twentyeight.threefive has it bang on, you need some minerals in there to leach because certain elements are immobile so need something else to carry them. And you don’t want to drop it too much cos the osmotic pressure deficit changes and stops any leaching happening at all. In hydro this is what I would do, and did do. But nowadays I just grow Percy in living soil so I don’t even bother changing anything just water from start to finish.

There's no need for any nutes during the last few weeks if you been feeding correctly. Let the healthy leaves finish feeding the plant and save your nutes for the next grow.
Please please please do this with COCO for the last few weeks.

would love to see the end results.

In soil this is definitely possible as the soil holds onto nutrients so just “feeding” Plain water will allow the plant to carry to the end more often than not.

If you run any kind of inert medium then this will kill your Yield, terpenes and possibly make the plant take longer to finish.

Didn't say anything about coco but even still then you want to taper your feed. A ppm meter will confirm what's needed not the nute manufacturers suggestions.

Just a word of advice.
Be more specific when you give advice.

not quoting anyone and just using a blanket statement without any context doesn’t help anyone.

no need to tell me about coco bud. Been using it since 2009.

In soil I just use plain water the last 2 weeks or so. Not really flushing just letting the plant use what’s left in the soil.

when I do passive hydro. 100% perlite hempy. I will flush with RO water to get my run off ppm in the 200-400 ppm range. Usually the last 3-5 days. Let it dry out and chop it.

works for me anyway.

years ago I was over feeding like most new growers. I would flush flush flush. Guess what. I just got some flushed crappy weed.

Keeping feeding low and steady trough your entire grow, results in a better product.

Took me many years to realize how little feed a plant actually needs. IMO directions on a bottle are to empty a bottle faster to buy more.

In hempys I was feeding 6-800 ppm in veg and 1000-1400 in flower. That was still below the recommended dose on the bottle. Same neuts at about 1/2 of ppm and I get better results.
go figure.

Check your runoff at 2 weeks to chop. You'll probably find ppms between 1000-2000 depending on what you're using. Feed the plant as the nute company suggest then read the runoff from there.
Is the runoff ppm higher? Yes=stop feeding.
Is it lower? Yes= feed more nutes.
How about his runoff pH? Or how about actually looking at the plant and going from there without all the technocrap bullshit?

Agreed. A ppm meter and basic math skills cuts the guess work out
