When to flush? How to flush in coco?

When? Never! not needed! MYTH!

How? Grab 333's head and shove it in a dirty toilet and press the plunger down!

You can not "flush" nutrients from plants = SCIENCE!
If you don't feed them for some weeks (fade) The plant is STILL moving the nutrient in the plant TO the buds !

As far as any home done side by side? Your brain finds a difference in things when "told" to. Even when the things being tested, are exactly the SAME = SCIENCE !!

It's called, Confirmation Bias

Once you get an idea in your head, you seek out only the evidence that supports your thought.

In the end, flushing is subject to so very many variables that there can be no general consensus made on it one way or the other. Through simple habit, I don't so much "flush" as I do just stop giving nutrients the week of harvest. I always harvest on a Saturday, so I stop all nutrients or additives of any kind on Sunday.

It's probably more of a "feel good" thing than anything else. I've had a few smokes from folks that swear flushing for weeks is the holy grail of all marijuana and I've smoked some from guys that say it's all bullshit.

I've never really seen any difference.

It's all subjective to our own thoughts, really. In the end, most any difference between the two has far more to do with what was done for the several months the grow took than it does what was done in the last 10 days or so.

That people have to argue to the point they'd come to blows were they in the same room over this topic is proof positive on just how far around the bend civilization has gone at this point.

Thanks to TacoMac for the above!


I got asked about this in a PM by a member after seeing the disaster another thread became. He asked where to find books and papers on "flushing" and said he might try the "fade".

Here's my answer to him......I felt it needs to be seen,,,,,,again!

Your looking for post grad work. You would do better to search papers......The thing is, NOTHING in agriculture gets 'flushed" and that leads to little to no research in the area. You see, the thing is, the whole "idea" of "flushing is nonsense! Plants don't work that way! They do not take up nutrients or salts as most of you think of them! They do not "store" them in the sense you think of them! Not only that, but the nutritional "stores" in a plant are not in buds or budding or flowers! NO amount of "flushing" will "exchange" plant "stored" nutrition back "out" of the plant! Scientifically impossible by the way most of you guys understand......Ok, that's my word on "flushing". (No one listens to this in threads if they don't want to hear it or accept it.)

Now then, you propose the "FADE TO FINISH" method. Great idea in theory but, and this IS a BIG BUT! Remember when I said above that "the nutritional "stores" in a plant are not in buds or budding or flowers!" ? This shoots that theory in the ass right away. You see the main amount of stored nutrition is in either the roots and the rest in leaves and some in small amounts in transit in the phloam (the sap that actually moves the nutrients around the plant)......

Now when you "starve a plant" it will draw from it's self by actually breaking down the needed parts of it's self to do an "emergency" attempt to reproduce! (This can happen in certain plants even in veg! A kind of last ditch effort to continue the species.)

With that in mind you take the fact that the plant is not "moving" nutrients "out" of buds, but into them to speed growth and as fast as it can - "reproduce". This single minded process the plant now puts it's self on causes the plant to stress it's self. This self induced stress can, in many cases if done long enough, lead the plant to go bisexual, and produce "banana's" in a last ditch effort to reproduce and "carry on the line" and produce seeds...

Basically put, In reality you are moving nutrients that you're "attempting" to get rid of,,right to where your trying to remove them from! You are also stressing the plant in the way for "Herming" to actually happen easier!

I and many others that have tried to convey this actual plant science, are called everything you can think of and those 'impossible of understanding these facts", fight so hard against us that many of us have simply chosen to avoid the issue or don't fight to hard.

Anyway, there you are in as short and sweet and as simple/understandable as I can...

The thing is you have to understand Botany and Horticulture (and there are LOTS of subsections to those that are involved here) to truly put together the pieces of the puzzle to get your head wrapped around the idea that flushing and the "fade" don't work for what they are intended or alleged to actually do!

There you go Mods, nice, polite and to the point. (Sorry about the other thread Sunni)

There you go, Now have at it!
I'm stepping back to watch the circus.

Read this too!

Hey guys here's an updated on my girls I started to notice nute burn so I backed off the nutes some In a ~6 day time frame dropping them about 200ppm every 2 days from 1000ppm to 800 to 500 still seeing signs of burn I started looking at the trichomes to see when to start my flush my flush schedule is ~10days depending on color looking for an all cloudy with a 20% amber heads at time of chop they were mainly clear on sept 26 and in that time frame they have changed to this the pictures below. my flush schedule is the canna flush (cannazyme/boost) for ~5days depending on run off ppm, then use final finish and flush with RO water phd ~5 days also going by run off. I'm currently on day 2 of my flush the cannazyme/boost part at ~100ppm
So am I over doing it on the flush? Too long? (I deff over fed most of grow)
Also from the pictures am I starting too soon?

They are looking very close

Flushing? wonder what stoner thought that up?

In gardening the term is leaching..and its not done for the reason some stoners attempt to use it for...

sorry if you read the whole thread this is my first time and the only place I haven't heard of flushing is on forums there is more science on Flushing then not flushing but there is science on both and I do see valid points in each like I said once I have some grows under my belt I will attempt the same thing same strain say newts same conditions just flushing and not flushing i'm looking for a good quality and product we all work hard I'm just starting out so please forgive my noobness
@bryangtho thanks for your help and congrats on your finish thoes aren't nugs there pineapples lol
also dose my time fram sound about right?

No such thing as "science" for flushing! Not possible by the plant!
You didn't read my whole post did you?

Anyway, who cares...do what you want....

Flushing is a myth and nothing more.

CANNAZYM
CANNAZYM is a high-quality enzyme product that speeds up the process of breaking down dead root material and activates beneficial micro-organisms. CANNAZYM also helps plants take up nutrients and increases the resistance against diseases. Enzymes are substances that speed up the reactions in living organisms. For example, enzymes play a vital role in our digestion.

BIOCANNA BioBOOST
BIOCANNA BioBOOST was developed by CANNA Research and is made of a naturally fermented plant base product that is enhanced with a mineral component.
The combination of these components provides a flower stimulating component. BIOBOOST is a true boost for plants.

Although BIOCANNA BioBOOST is made as natural as possible it is currently not certified organic and therefore not suitable for Organic Food Programs. It also does not contain any micro organisms.

For one thing, the most common way that growers flush their crops is by giving their crops water that has no nutrients in it. But this doesn’t fully cleanse your crops. It only starves your plants so they lose vigorous floral growth and resin percentages just before harvest.

How does this amazing process work to free your plants and make them more valuable? If you could see down to the molecular level, here’s what you’d witness:

Flawless Finish contains a broad range of ingredients known as “chelates.”

Chelates are like chemical “claws” that can grasp other materials, such as individual nutrients, and bind to them.

Some of the chelates enter your plants and create a downward mobility of excess salts that exit your plants and are washed into the Flawless Finish/water solution.

Inside your plants, from the time of flushing until harvest time, your plants are consuming on-board nutrients and otherwise purging themselves of unwanted residues.

By the time you harvest, your plants will be free of at least 85% of the stored materials they held before flushing.

che·late

noun
CHEMISTRY
plural noun: chelates

1. 1.
   a compound containing a ligand (typically organic) bonded to a central metal atom at two or more points.

@KryptoBud thank you for posting that I had found a page on cannas site about that info and another site just didn't bookmark it months ago when I found it. I know there is science on both flushing and not flushing, I see a more valid point of view on Flushing though versus not flushing. I have done a ton of research and on the not flushing part done by scientists their studies are not done on the cannabis plant. and every flushing technique has been done with cannabis and proven to be benifecial. so in my eyes flushing is a needed step
i'm done arguing or trying to get swayed into flushing or not flushing IM GOING TO FLUSH

my reason for this thread is to get an idea if my schedule sounds about right for flushing timeline wise and how I'm doing it? does it sound right?

I'm don't know about your flush schedule, i don't do it.

I posted the info from the nute companies website just to show the contradiction in their description of their product. Advanced nutrients final finish in particular.

Using plain water starves your plant and robs it of vigorous floral growth.

Using flawless finish with no nutrients doesn't?

Flawless Finish contains a broad range of ingredients known as “chelates.”
Chelates are like chemical “claws” that can grasp other materials, such as individual nutrients, and bind to them.
Their chelates are able to tell what individual nutrients that particular plant will need and remove the rest? Remember by their own admission removing nutrients or using water with no nutrients added reduces floral growth and resin production.

Next statement they make.
Inside your plants, from the time of flushing until harvest time, your plants are consuming on-board nutrients and otherwise purging themselves of unwanted residues.

Which is it washing them out or using them up from not being fed?

By the time you harvest, your plants will be free of at least 85% of the stored materials they held before flushing.
This statement's is pure bullshit here's why

Mother nature hasn't found a way to move some elements around a plant since they've been eating dinosaur shit, advanced hasn't figured it out in a decade.

Anyway's your plants look great you've obviously done some research. If you have any links for pro flushing i'd be interested in reading them. If you don't want to clutter up your thread anymore that's cool too.

all good man good info

So what I have gathered from this thread so far is some say yes and some say no on flush....lol....What I have learned is nothing.

Mother nature also doesn't use fertilizer salts.....

hey guys so on day 4 of the cannazyme and boost flush everything seems to be doing great very few leaves have changed color they have slightly curved upwards and tips falling off but not all leaves pretty sure it's heat stress temps have been between 75-81 during day and it has gotten down to 61 at night going to use final flush in ~2days for a 2 waterings and then plan phd ro but all depends on trichomes
couple questions on harvesting
after I do my last ro flush I was going to wiat till lights go out and turn them off for ~18 hours then cut while lights are still off from main branch and then start the trim from what I've read the buds will have the least amount of chlorophyll and water in it if cut when lights off
here are some photos from today
about a week out maybe I think?

Got some canoeing going on but you called it. I would 10L/14D the light cycle to ripen faster, if you so choose.
Yeah, cut in the night cycle, at least 4 hrs into it so the plant can have time to drop the starches back into the rootzone..

hey guys just an update on my final flush day I'm currently running 5 gallons of water through each pot about an hour apart I'm at gallon three and my ppm run off is down to ~100-120 PH is fine i'm using straight ro phd to 5.8-6.2 and I plan on going lights out for approximately 36 to 48 hours here's is where my questions are

when I go to do lights out for -36hours should I keep my lights on until my pots have dried out for a day or longer or can I go shut off the lights today when they normally go off and begin the lights out?

also when harvesting should I harvest with the lights completely off and use a green light or is it OK to turn on a light?( was thinking about just cutting the very base of the stem letting it sit for an hour and then turn the lights on to see what I'm cutting?)

here are some pics of today any input would be great maybe I'm over doing it too much not too sure

i've also been dealing with some temperature issues so some of the leaves have started to curl
