I am going to go one more week and I am looking for opinions on flushing.

I am running DWC and I was thinking of doing the last week just plain water.

Here's my opinion from having read up here. It all depends on goal and how well you know your plant. I am sure there is legitimacy to letting the plant use up what is stored and improve flavor.

The challenge is that buds thicken up at the end. We judge when to harvest by trich color. So to be effective with flush, you need to know or predict when you are two weeks away from harvest. If I just go by the what the breeder said for flower time or the nute feeding schedule, I could flush too early, harvest too early, or otherwise impact yield.

I am 5 weeks into flower and trying to decide what to do myself as it is only my third grow. I think I am going to rish a shorter flush to make sure I don't do it too early and lose yield.

Very open to how others handle figuring out when it is the right time to flush or tell when optimal harvest is two weeks out.

If you understand the plant... you will not flush...
Unless you have screwed up...
So, don't screw up, and don't flush...
-----
You grew your plant from seed, 10 weeks in veg room, you held its hand when it was sick, you nursed your plant back a couple of times...
9 more weeks in bud, you have been careful, never over nute-ing....
Feed it till the end... NPK does not end up in the buds...

You want smooth, smoke that will rock your sox off.... follow the cure in this thread and you will not need to 'flush'....
It's as simple as:
A-Grow properly,
B-cure properly,
C-smoke good sheiot...

flush, or smoke that nasty chemical taste. black ash choke on it, make you sick , popping, weed, and by the way, if you sell it to a dispen they send it out to test it, no flush it will fail. and you will have no buyers, don't make people sick, have some respect, rec 7 day flush ph water, min, I do 2 toooo 3 weeks, super good taste

Don't flush, just keep ppm low (600-800) for the last week.

If the plant looks healthy, it's not going to taste like "chemicals". The plant need some nutes to cure properly.

The reason buds don't smoke right is because of a high starch content, not because of "chemicals". A sufficient nutrient level actually promotes starch breakdown (blocks starch buildup) and provides an environment for healthy metabolism.

Cutting before the lights come on (giving a dark period before cutting) also helps to reduce starch as the plant eats up it's night supply. Leaves only produce enough starch to last for one night (it times it). After the night is over, almost all the starch in the leaves is used. Iodine tests prove this is true.

Leaves have the highest starch content right when the lights turn off.

its been pointed out on this forum many times before that no other crop is flushed. there's no rational fact based reason to do it and it will effect yield. bad flavor comes from poor drying/curing, bad storage, mold, or stuff ppl spray on their plant (neem, pesticide...).

you have been out voted, I am not selling, I am not in a state that has "dispenserys" for "medical marijuana"

you're asking two different ?'s imo.. the thread title says to flush or not, then the post doesn't even mention what most people would consider a flush..
a flush that most people talk about is that bs imvho about dumping like 3xs the volume of soil in water through a medium in some mythical attempt to wash out something they think is in the buds by dumping water through the medium, something that i never quite understood myself..
and the other method is what you're talking about, just using plain water for the last week or so, two very different things imo.. i don't really see the harm in using basic water or maybe a very light nute feed in the last week or so as i usually cut nutes back in late flower anyhoo's..

so not until i know what you mean by flush will i vote.. if you're talking about dumping tons of water, than it's a nah.. i'm not a big believer in flushing do poo all for the taste of buds or the color of ash or w/e it is flushers like to think they're doing.

i dont know the taste of his finished product obv lol but he kills RDWC taking it to new levels
Nope, not impressed. The video you pointed out shows a nice 'grow', everyone can "veg" plants. He's bragging about the stem while it's a skinny emeffer. :-o I'm not familiar with Apollo gear, but the BS about the cheap bulbs seems just that, BS excuse. I rather pay a little more for a more complete spectrum and more lumen, the $20-$30 extra for that I easily regain from using it.

Not by flushing something from buds of course (some really think that?), but flushing (mineral) nutes from the soil so the plant starts feeding on itself, pushing the fall effect, instead of keeping it green till harvest time (=chlorophyll taste). Keeping the (sugar) leaves allows me to dry slowly, which is the key to good taste, but leaving too much green on increases chlorophyll taste so it's better to let it suck it out of the leaves instead of continuing to feed it till the end. (just saying what I know is for many I know a main factor in that 'mythical attempt'.)

Obviously you cannot flush all nutes from soil, especially with regular tap water, so it reduces the amount of nutes available to the plant. And that's imo what one should do on hydro as well, 'reduce' the ppm to a little less than it needs, measure the next day and see if and how fast it dropped further (which it will if you 'underfert' it) and adjust accordingly. If it dropped too far too fast add nutes, if it didn't drop at a rate that would bring it to ~200-400ppm at harvest time, add some water.

I'll add this though, if this were a poll amongst coffeeshops in NL 100% of the votes would go to "Yes, flush (or I won't buy your shit)". The word "flushing" by itself gives the impression it is 'cleaner' and I think that is a large motivator for people to do/want flushing.

But, as a good test, go to the max with boosters with two plants, flush one and not the other, dry for a week and taste... Curing? Well, not everyone has the luxury to do that, on the contrary, storing mj is in many places one of THE risky parts, so many suppliers want to get rid of their stuff asap, which is as soon as it's dry enough. Point being that the slower you dry and the better you cure the less important 'flushing' (of any kind) becomes. Making the answer to "should I flush" always "that depends". It's not a requirement for good tasting weed, it's not entirely pointless under all circumstances either.
