Whether people flush is very debated in the industry/community. Thus my big disclaimer on my last post suggesting each person try things themselves to see what works best for them. There is no scientific basis behind the concept of flushing and its not practiced in any other agricultural setting.......Gg auto , and thought it was the done thing, this is my first grow in over 20 years
Flush toilets not plants.And in soil
This is exactly my point. We scientifically know nutes help our plants grow. Why would you stop giving them at the end? I ask new and experienced growers on here periodically why they flush? Not one of them has ever given me a logical answer.Whether people flush is very debated in the industry/community.

Your plant still has a couple/few weeks before you should be even thinking about it though. Which gives you plenty of time to keep researching it to decide how you want to proceed. Your plant still has maturing to do, and weight to put on for you.
Ty you very much for your advice buddy, is it normal for autoflowers to shed their larger fan leaves late bloom . Supposed to be a 8wk strain but is already about 10wks now and you think it has another 2-3 ???This is exactly my point. We scientifically know nutes help our plants grow. Why would you stop giving them at the end? I ask new and experienced growers on here periodically why they flush? Not one of them has ever given me a logical answer.
You just can't "flush" nutes out of a plant. It doesn't work like that. It's a monkey see monkey do task.
Same thing with transplanting autos. I've been growing them for 10 years and have transplant 100% of them. I have done side by sides. At the end of the grows they all look the same.
To each his own.
I can go on and on. Stay safe. Later gators.
Well I read the OP, so I do know that he is growing autos thanks. That does not change what I suggested in any way. The plant still needs to finish swelling BEFORE you switch to water only. Then it can ripen on plain water to a proper finish.
Proper slow drying has far more of an impact on the final product then flushing EVER will or could. This is where so many new growers have issues. They get excited and want buds and can easily dry them so fast they turn out gross or they put them in jars when they are real wet and can turn gross. You want your plant/buds to take 10-14 days to slowly dry. 14 is better then 10, 20 wouldn’t be a bad thing if the conditions are right.
Personally I stopped flushing many many years ago, but it was heavily because of the style of perpetual grow it just worked best like that. I ran multiple side by sides with identical clones with identical conditions right up until the flush point. There was no benefit to flushing other then saving $3 on nutrients that week. The more research I did the more I found that there was nothing even remotely scientific about flushing a plant which made it seem even more pointless. I’ve grown many hundreds of plants and people rave about my weed.
I don’t argue with people about how they should grow in their garden, but suggest you do the research into botany and growing in general, not just cannabis based literature and sites. Do some side by side grows and tests, and then blind taste test your friends and see what they like more. But before you worry about any of that learn how to finish a plant to proper ripeness, and then how to slow dry it for a great smoke in the end.

It really all boils down to don’t put something on your plant in the first place that you aren’t going to be willing to have in the plant because you can’t remove it once it’s in there. There are lots of threads discussing flushing with as much or as little info as exists.I'd like to learn more about this; "flushing" in general, for several reasons.
Is there a good thread, or any good resource that at least attempts to discuss the topic - and using some scientific (tests, etc) data?
I understand the "reasons" why grower do it, even though they might stem from have "just heard that you flush for 'x' amount of weeks" and going with it. But even then, the actual "reasons" (whether they knew it or not) if you were to ask someone who advocates flushing, aren't "just because". I think it's usually something along the lines of "taste", "black ash", or even just "the fading and changing of colors within the plant/leaves".
I can (and did) think of "reasons" why it "made sense", maybe not "logically", but what seemed to be intuitive - for lack of a better word (?). Yet even then, I've seen/had harvest in hydro setups where I could not get any type of "fade" regardless of how much very low strength, or plain water I ran through the system (whether pure hydro, like r/dwc, or rockwool). And after the harvest, and a decent dry (maybe 7-9 days?) and some curing (duno about that because it might have been slightly to dry to get a cure afterwards?) there was no bad taste, no black or dark ash, and "popping/crackling" at all. So it just left me with more questions, haha.
Coco, with stupid amounts of "flushing" produced all the fading and changing of colors that people seem to be after while flushing, though.
I thought the actual, rational reasoning for a "flush" would be to remove all the nutrients from the media so that the plant has nothing more to uptake, and therefore would have to use whatever nutrients it had stored in the leaves/tissues to "finish up".
I duno what's what at this point so I'm just kinda expanding on the explanations I've heard for "flushing" that seemed to resonate with people, including myself, when they were advised to do so. I definitely think the actual long dry, and cure as well(?) play a big role.
The comparison of other crops that aren't flushed gives me questions too.
-Are these crops a smoked product; are they consumed in a similar manner to cannabis at all?
-Are these huge industrial producers (of food crops) who engage in all manner of "maximizing potential earnings" with no concern for the end consumer (ie, they don't give a fuck if it's healthy, etc., or not. Only that it's big, heavy, bright in color, full of water/tastless, is harvested as quick as possible, etc.)
-I'm just thinking, for example, it doesn't matter if theres all kinds of chlorophyl (and Nitrogen??) left in leafy green produce...it tastes of chlorophyl anyways. That kinda stuff, what about that?
With ornamentals, for example, industrial scale growers (can, and do) manipulate different elements to alter or augment; colors, size, shape, etc. for salability. It would seem intuitive that certain elements left in the actual plant tissue could potentially be undesirable - or at very least have an effect on taste or something similar. But that doesn't mean it's factual.
I'm rambling. Sorry if I distracted or got off topic @Buddy73. It's a tricky topic, and a very interesting one.
BTW I agree with the those saying you've got a couple weeks left (at/from the time they said it, hah.) And those are nice, chunky looking buds, dude. I have no experience with autos.
Peace.
The typical flushing time is two weeks before harvest!!!! Im tired of people telling people their ways but the professional cannabis growers say start around 2weeks before harvest not 10days. Until you do it and are comfortable do it as the pros tell u to do 2 weeks. Follow the real pros until your awesome at being able to tell when maybe to flush etc. Do it by the book!! Best of luck!Hi all I was wondering if you all think it’s time to start to flush my gg#auto yet?View attachment 4471778
Most "pro" or for profit growers would not sacrifice yield by starving a plant in its final weeks.The typical flushing time is two weeks before harvest!!!!

C'mon man. What do you think I'm talking about? I'm talking about plant nutrients, the 12-13 elements that are in the nutrients we all feed our plants. Don't be silly. "you can't remove it once it's in there". Are you serious? Like are you thinking that other people think they're going to shrink down in size, go inside the plant like the magic school bus and "remove things they put there"? Haha, I'm kidding.It really all boils down to don’t put something on your plant in the first place that you aren’t going to be willing to have in the plant because you can’t remove it once it’s in there.

Shit, I'm flushing my toilet daily! Is that too often? I haven't even checked runoff or anything.Flush toilets not plants.
WTF?? Follow the pro growers? I thought I already said flushing is not needed.The typical flushing time is two weeks before harvest!!!!

I’m not over simplifying anything man. I’m just not trying to get into a big debate and side track this dudes thread. I fully understand how plants uptake and use nutrients. Tissue tests and basic botany have proven that flushing doesn’t remove anything from the plants. And removing nutes from the medium is only relevant if you have over fed them.......So once again if you don’t want it in your plant don’t feed it (or over feed it) in the first place.C'mon man. What do you think I'm talking about? I'm talking about plant nutrients, the 12-13 elements that are in the nutrients we all feed our plants. Don't be silly. "you can't remove it once it's in there". Are you serious? Like are you thinking that other people think they're going to shrink down in size, go inside the plant like the magic school bus and "remove things they put there"? Haha, I'm kidding.
But.. the plant is uptaking elements, allocating them, moving around the mobile ones where needed, using them, storing them, etc., right? I think you're over simplifying it and kinda misrepresenting the *concept. Tissue test are done to see what the level of "x" elemental nutrient level is in the plant as compared to what it's being fed, and what's in the medium. Maybe you've seen some of the literature/videos from various university "extensions". For example, when they're trying to ascertain what the minimum level elemental ppm of, say phosphorus, is to have a certain desired effect.
...
I'm not saying one way is wrong or right. I don't know really. But I guess it's understandable why there's such "debate" about the topic...
So, there's no scientific data in support of one or the other (yet)? To each their own then I guess, lol. Hopefully there will be in the near future.
