I'm guessing about the next watering before the third nute treatment. What do you guys think? More or less? I could probably find out by experimenting, but thats too cruel for the plant.

wat stage are they at??
u only need to flush in hydro at the end of cycle flush 7-10 before chopping
no need to flush in soil at all

You need to flush 7-14 days b4 harvest on soil, this is important as lots of chems and salt can build up over the plants life.
On a hydro system 5-10 days is enough.
no need to flush the dirt, we dont smoke the dirt do we now lol ,,and you cant remove wats already in the plant no matter how many ltrs of water you push through the soil.
its good pactise to starve your plants of food last week by just giving water

The reason for flushing the soil is so the plants use stored chemicals in their leaves and buds etc. to finish off. This speeds up the curing process as there is less nitrogen in the plant when harvested. It also makes the weed smoke smoother and brings more of the plants natural flavour through.
If the soil is not flushed the plant will feed from the soil and the chemicals will remain in the plant after harvest! Infact the plant will be FULL of chemicals. This will produce a harsher smoke and a nasty taste, usually a metallic aftertaste.

Flush a good 10-14 days before harvest to be sure !
I use this product from General Hydroponics called florakleen and use it at the end of the flowering cycle. I also stop using any nutrients, just keep adding water to the reservoir for 2 weeks lowering the PPM of the water gradually until I reach a number in the 400 ppm then I use the flora kleen, then no water for a couple days and cut:rastasmoke:.
SO YES VERY IMPORTANT TO FLUSH !!!:thumbsup:
pd. There are many cleaning additives , I just use this one but there are others out there.
Peace :hippy:
yes there is a need to flush salt build up can couse rootlock and stunt plant growth i flush once every two months then flush 10 days before harvest:thumbsup:
i grow using organic soil and organic nutrients , they contain no salts and are mostly molasses based and i feed right upto the chop , as advised by sum of the highly regarded organic experts ( ot 1,von) , flushing is advised when using crappy chemical salt nutrients yes , but not with organics ... just cas i just joined here and aint got many posts you assume i know nuthing , i been growing along time m8 , and am a member of alot of cannabis boards where my skills are appreciated, cheers for the negative rep ,,, do you actually grow m8 of just post wat the general concensus is around here ?Quote:

Now it seems it also refers to starving plants during the last week or two of flowering. This of course gives an inferior product compared to what each plant is capable of producing within its genetic potential, ie: less psycoactivity and potency, much more CBD and CBN, less THC, less turpenes and finally lower final crop weight.
Some people in the hydro world now think that by running on just water that they can flush out excess chemicals from the plant by some form of reverse osmosis through the roots into the flushing water. Its amazing the myths that grow in the cannabis community.
Outdoors when growing in soil, where cultivated organically it is nearly impossible to remove any nutrients by rain or water running through the soil. It is only with modern farming practices, that huge amounts of chemical salts get flushed/washed from the soil into our water courses/rivers every time it rains. This happens with both chemicals and through the bad practice of slurry spreading.
The major expansion of bud growth happens at least a couple of weeks before they are ready to harvest, you can see when this has happened, after that it is better to have a ratio with lower levels of N and P but higher levels of K and of course lower levels of feed would be needed as the plants metabolism is winding down. Excess levels of residual P make the bud harder to burn and give a nasty taste in the mouth. Also it make the smoke many times more carcinogenic. Bud with low residual P burns to a white ash especially if it has a reasonable level of K, the more P the greyer the ash and the harsher the taste when burnt.

You are talking out of your arse m8! Ive grown weed organically and non-organically for years. Flushing the soil DOES force the plant to use stored chemicals, which in turn flushes your plant.Quote:

You have negative rep because you refuse to accept that you are completely wrong. Its basic chemistry, and common sence.
Enjoy your non flushed "organic weed" .
read up on organic growing m8 , youll find the answer
put "when to flush organic fertilised cannabis" into google.Quote:

Un-flushed pot leaves black ash, is hard to keep lit and burns your throat. Pot which has been organically grown and properly flushed is more flavourful and fragrant, burns easily, leaves grey ash, is easier on the throat and is much more pleasurable to smoke.
seems your wrong... again
yep good article , dated 1999 , back when everyone flushed even in organics , since then things have changed mate , i wont mention the name but theres a few organic experts on other weed forums ,, they can give you a more up to date view on organics ,,,the concensus these days is theres no need to flush if using good organic soil n feeds and if you feed correctly ,,,its 2007 btw
I've talked to experienced growers that flush their mediums before they change nutrients mid grow... It's a technique that's used in both hydroponics and soil...with a fully certified organic nutrients like the Bio-Canna line from Holland you don't have the same necessity for flushing.. as you are using fully organic material. However, It is still an option for the grower.
Flush or don't Flush.. it can or can't make a fairly large difference.. it all depends.
You got negative rep (from me anyway) for this comment
"no need to flush the dirt, we dont smoke the dirt do we now lol ,,and you cant remove wats already in the plant no matter how many ltrs of water you push through the soil."
Not only was the comment a snide one.. but it wasn't entirely correct in being informative.
You personally can not remove anything from the plant.. but you can help the plant to use up the nutrients it has already by flushing out the medium with 4 or 5 times the amount that you usually water.
Wether or not you do this before you harvest has a lot to do with the type of nutrients you've used through-out the grow and how heavy of a feeding regiment you've had it on.
Elstonite, I've grown. I've also compared between a flushed and a non flushed plant. I gotta say, I prefer the taste of a flushed plant.
P.s. I sell hydroponics and HiD lighting for a living, so i'm pretty sure i know what i'm talking about.
The year makes no difference, the industry has NOT changed that much in the past 8 years. Only growers and opinions have.Quote:

horses foe courses then , sum do sum dont , personally i wont whilst im using organic nutes n soils ,,,ill agree to disagree and take back any remarks implying you dont grow and dont know shit , but i still think the neg rep was harsh , others followed your lead in that thread leaving me - 11 points for wat was basically a honest well intended answer ,,not in your words (giving out wrong advise)
Hence.. the reason for flushing!!Quote:

I've always understood this.. I've just been trying to avoid misconceptions that seem to be stemming from this thread.
Fully Organic Nutrients = Optional Flush
50/50 Organic/Synthetic Nutrients = Should be flushed (Can use a clearing solution.)
Fully Synthetic (eg. D.N.F or Advanced Nutrients) = Must Flush
If flushing was a myth, they wouldn't make products designed specifically for removing excess salts from the medium before harvest.
P.S.
I wouldn't worry to much about the Rep here.. it's only for "fun". Within the first week of it being enabled... I was at -165 points.. you can disable it if you'd like by going to options in your "User CP."
Bob.
ill agree with that bob
I FLUSH , YOU FLUSH !
We ALL FLUSH !
:jointsmile:
It would seem that you misunderstand the myth. The myth is that by fluching all the nutrients from the soil, they will no longer be there to feed the plant, so the plant will use up the nutrients that it has stored. As far as myths go, this one at least seems to be grounded in logic.Quote:

Interestingly, there have been some discussions about molasses lately and almost all of the pro growers agreed that molasses can be used right up to the end. So, in a way, that kinda makes you right too, doesn't it?
And then there's the quote from your first post here:
So it seems there was some kind of partial agreement right from the outset, just the use of different terms.Quote:
