flushing coco for a smooth taste

[cookie_monster]

This is what I do, except I go lil further and after the flora kleen or black label flush I run one more gal of straight un ph'ed RO to get some of the sugars out that are in the flushing agents... Just somthing I've allways done and I only go for two to maybe 4 days no crackle here and tend to be a bit heavy on the nutes since I only use one gallon every 3 days so the nutes still last awhile..

I think i'm going to try that. Im gonna use a flush agent then flush that out also with ph water or maybe straight ro/di a day or two before harvest

 

[joe guy]

I use #2 smart pots so roughly 50% run off for the final flushing what ever your pot size maybe has worked flawlessly for me.. I don't sell mine so I really don't have any feed back
Except for the few buddy's I smoke with and only 2 know I grow so with 2 out 4 people I smoke with I get a 2 unbiased opinions and they both say fire "the guy has some dank nug" lol so give it a try but only do it one plant try diffrent methods for each one
Never put all your eggs in one basket cause some guy on the Internet said it would work lol..
And chose your method from that..
Good luck buddy

Definitely. I have a friend that refuses to flush his product properly. He's using cheap nasty salts to boot. His product burns coal black on the rough end of the spectrum and his primo stuff burns mottled grey/black. It's terrible through a vape, tastes terrible, burns your throat and makes you cough. As a general rule I only smoke his stuff when I'm basically out of my own. He gives me a lot of samples that get given away or tossed in the bin.

As a general rule if the plant is lush and green you need to flush longer before you chop it. Once you start to see some yellowing you should be alright to take it down.

I cut nutes to around 400 for 1 week the just cal mag and budxl last week. Nothing but gray Ashe and no popping or harshness!

i flush with plain tap water for 1.5 weeks in coco.

Basically your plant will use what nutrients are in the coco and then move on to digesting the nutrients out of its main leaves. you will start to see fan leaves and water leaves being consumed and changing from dark nutrient heavy green to light green then to yellow and finally dying off completely. PERSONALLY i believ so long as your plant has consumed most of its own nutes from the leaves (mostly yellow left) and none of your small bud leafs are turning yellow then your happy, all the extra bullshit with ec etc is just the same overcomplicated stuff

In coco I think you need to dial down your nitrogen the last half of flower. Coco plants seem to stay green longer than other mediums I've grown in, but that could be due to coco nutrients. Two weeks flush will still give me lots of green leaves if I didn't start dropping the N early.
If you've done that and you didn't overfeed, I think a week is plenty. After 1 or two days of plain water my plants purple up very quickly and start falling over from lack of nutrient. I use RO water for the flush

 

[Ziggaro]

Some notes-- and sorry if I disagree with anyone's response but--

Mag is one of the harshest thing you can smoke. I don't think you should add it at the end of your grow.
Root stimulators often contain hormones. Don't give your plants IBA and NAA and whatever else is in there at the end of your grow.
Tap water is full of calcium and other minerals that your plant will barely use at the end of flower. Try to find a clean water source.

I 'flush' my cannabis in coir, but only around 3 - 4 days of water maybe a little more if I'm a bit early on schedule just in the last few days.

I love how some of you are saying that if you don't flush for like 2/3 weeks then your bud is going to burn badly and/or taste bad I think that is rubbish. Our plants converts the mineral salts to new plant matter/growth, if we have an excess its stored in the plant and then the medium and eventually what happens is the salt becomes too much and draws moisture OUT of the plant and back into the medium, because thats what salt does. Whats left is what we call "nutrient burn", its actually really dehydrated plant.

But that might not show itself for 4/5 weeks of constant overfeeding, unbeknownst to stupid arse until it is too late. But signs of overfeeding may not even show itself at all perhaps from a bit of darkening/tip curling or something if we have gone quite heavy handed.

There is absolutely no amount of flushing with plain water and causing a plant to cannibalize itself that is going to fix that, the plant already has too high concentrations of mineral salts, and the wrong ones at that you don't see hydro tom growers flushing huge greenhouses of toms no way, they're perpetual harvests, nevermind the toms splitting.


This is just my 2p but I see growers knocking their E.C up to stupid numbers like 1.8 + for something like a plant thats 2 foot and 2 foot in a 20L pot and it makes my head spin. I hear a lot that growers will increase the E.C by a small amount each week until they start to see tip burning and then back off to a 'safe level' well as I mentioned earlier you may be over your plants particular thresh hold by about 3 weeks in which case the safe level is actually a dangerous level. The E.C should be started LOW until the plant starts to pale up or show signs of hunger, and then the E.C is increased keep your ladies wanting LESS IS MORE.

Back to the point at hand RE flushing, I believe that if you keep E.C at a level where your plant is JUST getting what it needs there will be no excess concentration of mineral salts in the plant, nor in the medium. When it comes to harvest, I do think that using something like a flushing agent is good as these tend to be small amounts of certain elements that burn smoothely, unlike phosphorous which we all know causes that horrid black, burny pond weed nobody likes to smoke and then finish up on water for a couple of days because nobody is perfect


I very rarely get to smoke coco/hydro weed that is grown/flushed properly unless its my own due to the soft-touch cannabis market spreading misinformation so products sell.

IMO anyway lol

 

[watts]

i flush for one week, drop nitrogen completely 2 weeks before chop.

 

[Granger2]

I grow in 20% perlite, 3 gal AeroBags, with Earth Juice nutes, ACT's. About 10 days from harvest, I pour 1 gal of pH'd tap, followed by 1 gal of RO, followed by 1 gal of RO with Botanicare Clearex thru the medium. After that I just use pH'd tap till harvest. What I'm trying to do is to get all the nutes out of the medium so the plant has to consume itself. Since I've started doing this, I get white ash and clean mild smoke. To each her/his own. -granger

good stuff here. 1 to 1.2ec all the way thru for me. the last week or 10 days ill start reducing ec by topping up the res with ro water.

I believe with coir, just using plain water keeps the nutrients locked in the plant n medium, by throwing off the cec.

I think u use more nutrient up by using the correct ratios still, thus making it easy for the plant to uptake n use what it needs at the end of its life.

A healthy, never overfed plant, dried n cured properly, will burn awesome.

Hey everyone,

For me 1 week canna flush and finally 1 week just water

Thanks

Absolutely correct mate, flushing with pure water does mess with the coir CEC but also with your plant. If you decided to lose weight and then just completely abstained from eating it would be a while before you started seeing any weight loss because your body would go into survival mode, holding onto and efficiently burning any and all good nutrients to survive until your next meal.

It is the same with plants, that is what you see why leaves yellow, it is eating the reserve to fuel growth. Well the concentrations of mineral salts are just being transferred from the foliage to the buds so if anything we are having the opposite effect of what most are trying to achieve then they "flush" cos we're just loading our buds with more shit. I don't expect anyone to have a nice tasting crop if they're using something horrendous like shooting powder, have you seen how much phosphor in is that shit?! Unnecessary!



Be careful with RO water and coir though my friend as pure RO through coir can make things get a bit weird. I live in a hard water area (0.6 background ec pH 7.5) and don't bother with RO and just use nutrients tailor made to my water, as this way the excess calcium and magnesium in my water is incorporated into the feed so we do not overload on anything by accent and ruin the burn quality. I suggest everyone uses nutrients tailored to their water type if they don't already!!

Some very interesting points you raise Syrup

I know myself I'm a bit heavy handed with the A+B and I chuckled at your EC of 1.8 for a 2 foot plant comment... but then I stopped chuckling.. I EC to 1.8 as well (during the peak of flowering weeks 4-6).. although my plants are 5 foot monsters.... thoughts?

Ha ha ok well I'm afraid I can't tell you what E.C the plant wants only you can do that! When I teach people at work and they ask me questions like that ( I am more polite online! ) I ask them how long is a piece of string?! How do you determine that 1.8 ec is correct for a plant of that size? Do you increase by small amounts each week or starve the bitches out?

Maybe a good place to look would be DJM's coco trees thread, he grows massive 5 - 6ft monsters, and tops out at about 1.6 ec if I remember correctly! That is a great thread to read for information. Another good thread is the myth of high P myth and any post by yosemite sam.

It is a really tricky subject but I am of the opinion that proper management of nutrients needs to be address as ultimately people are smoking the end product and not doing it properly can be harmful IMO and the hydro industry on the whole (there are somee good guys still trust me!) does nothing to curb it when they're making 100% markup on £100 bottles of silly PK boosters.

I am ranting now and getting carried away lol sorry I can't be more help JamieShoes but obviously the larger the plant the more mineral salts are required but again it is all variable as I have had plants top out at 1.6 and others top out at 1.2 (sometimes I have seen a variation as big as that within a packet of seeds!) and all of varying sizes so it best to err on the side of caution and increase when and if you see signs of underfeeding - dying bottom growth, deficiencies showing around the tops etc.

all the best.

 

[JamieShoes]

DJMs thread is an awesome read man, that and the weird n wonderful story of coco and nutes (or whatever the other sticky is called)

I wasn't taking the mick mate, I was genuinely curious to know how high you think EC should go given plant size.. (your opinion is of interest to me as I can tell when a poster knows his bizzle, and you clearly do) I still think 1.8 is a bit high, even given the stature of my plants, so I'm tweaking it all the time.. strain dependent of course, some of my hungrier girls seem like they can happily munch on 1.8.. but I'm reluctant to give them less in case yield suffers...

I arrived at this EC after years of bumping it ever higher until seeing what I consider to be negative results at around EC 2.2 (scorchio ) and then backing off to where I'm at now 1.8..


edit: I may not vote on anymore threads today...ffs it's barely half time..

Hi dude sorry if I came across as hostile that wasn't my intention!

Considering what you'd said regarding your E.C then I would recommend that next time you start on your starting dose and just float it for a while and see how the plants react, if they do start showing signs of hunger then just up the E.C by .1/2 and then float it again until the same happens.

In my experience I have found that different plants like a different level, and as you have said things like size DO play a part in the amount of mineral salts required to sustain it, but I do think that each plant/size combination has a 'sweet spot' and you will know when you hit it as the plant looks as though it doesn't want nothing more or nothing less.


TBH though I don't think a cannabis plant will ever need over 1.6 ec, unless its one of those 160 ounce plants they grow in cali lol

 

[JamieShoes]

hahaha how british are we? I was apologising for the same thing


"sorry I hit you with my car"

"sorry I was in the way old boy" ..

Idk fellas, Ive ran sog, 6' trees, n everything in between. probably a good 60 to 80 different strains. All have done well with 1.2ec or less. All the way thru plant life. I know everybodies situations are different with their environments, but I think with coir its most important to have the right ratio of nutrients. when u have that u can trick them any way u want to keep them happy. For me, its feeding them before they get too dry, n that keeps fresh exact ratios of available nutrients, at the super low level of 1.2ec all the time.

My friend accomplishes pretty good results, n uses like 12 different additives, and ends up around 2.3 ec at his peak usage. He has to flush for quite a while to try n get the salt levels out before harvest in his situation. but it works for him.

But hes never came close to my yield results. Plus his same strains usually don't taste as good as with my feed schedule. that's his opinion too, but hes afraid to change what works for him, even though I average 25 to 30% more than him.

I put plants around the light, so my max goal weight is around 1 lb plants. One of the guys I copied this strategy from grows with lights around plants n gets 3 to 4 lb'ers, with 5' monsters at 1.2ec.

U can have success all different kinds of ways, but if u know that u can get top quality, n top yields n only use 1.2ec, n not have to flush the hell out of them because u have never over fertilized, n don't have salt build up. I just don't understand why anybody would want to use more than u need, except for the fear of the unknown.

Miracle do you use CO2?

Curious as to if you guys think that really changes the equation as far as nute strength. Ive seen varying thoughts on that.
