flushing
- Thread starter duce
- Start date
If your going all organic flushing isnt necessary. I flush every few weeks just to help the my plants out. Lots of hydro people do this and it can benefit soil growers too.
As for Blue Mystic, i think its in the white family of strains but i dont know. Check out nirvanas website for more info.

I think there's another thread around here regarding flushing.
Where is that thing?

Kush king sorry mate but you're the one who "dont no shit". If you're using 100% organic nutes then there are no "chem" in the plant or the soil to flush out. Do u think outdoor plants of any kind get "flushed out"? Of course not.
If u flush organics u wash out all the benificial bacteria in the soil. Thats the very thing we try to promote in our soils.
U were from OG, i'm sure u read heaps of threads by organic growers such as the 3LB & other awsome organic growers & u won't find any of them insisting that peeps flush or saying that peeps "don't know shit" for that matter either.
There are just too many diff ways to grow MJ with just as many opinions to go throwing words like "don't know shit"
Time to learn some manners Kush.

do the tests for your self.100% and you dont flush... y is it you get a black ash and the ojint hardly smokes...
Iv only been doing soil for 10 years and the saying is "grow organic Flush your pot. Thanks alot"
just grow organic try it... I sure did and i flush half the crop and used ferts till end on other half.... it was like night and day LOL
Just like saying Bat guons dont have nastys in it BULLSHIT. flush it out ppl common rofl...
heres a little sumthing to read up on.

Saying we grow organically is not enough, even some organic ammendments can leave a particular taste behind in the smoke, like using fish emulsion at the end of flowering.
I don't flush, I just go easy on the nutes throughout my grow as well as using the right soil additives, the real problem is peeps using bottled shit that has all sorts of additives and using to much of them.

If there is too much nitrogen available in the soil then there is a good chance you will wind up with bud that is harsh on the throat and burns poorly leaving a black ash. I have had this happen using organics too. All was not lost however, thanks to a set of bubblebags. 
I give plain water for at least the last three weeks and longer if I think the plants look dark green. I aim to have the larger leaves turning yellow by harvest but I don't always achieve that and I can taste the difference.
The plants will always have some nutrients available from the long term soil amendments like bone meal or greensand or whatever else you mixed up. I just don't give them any extra when I water.
In the Nov 05 issue of Cannabis Culture there is an article by Jason King titled, "Why Most Pot Sucks." Jason is a photographer who has travelled extensively taking pictures of buds which are in the Cannabible series. He has sampled a lot of those buds too.
In his opinion there are four main reasons.
1 Herb must be organically grown.
2 Herb must be flushed properly.
3 Herb must be cured properly.
4 Herb must be handled delicately.
To expand on reason # 2 this is what he wrote:
Herb must be flushed properly
"In order for ganja to reach its ultimate potential quality, the plant must be cut off from food and thoroughly flushed with clean water for several weeks or more before harvest. Of course this step is much more important when harsh chemicals fertilizers are used than with organics. But if ultimate quality is to be reached it is necessary with any setup. The amount of flush time varies depending on the situation, but I generally recommend stopping all feeding and switching to pure water approximately one month before harvest. This timing can be shortened for indoor plants or lengthened for outdoor plants, depending on container size, the fertilizers used, the strains grown, and a number of other things. This gives the plant time to finish all remaining food, and the leaves will then start changing colours and the plant yellowing. Yes, you might be able to crank out another few grams or so by feeding them up to the end or close to it, but we are going for ultimate quality here, not quantity. Cannabis plants that are allowed to yellow on their path to senescence have a much more beautiful and complex flavour when smoked or vaporized than plants that are fed and are bright green right up to harvest. Again, I have done experiments that have proven this again and again. Skipping this step is one of the main factors that has ruined most Canadian and Dutch herb. There are many connoisseurs who completely agree with me on this point!"

WTF?
I do agree that the aim is for our girls to use up most of they're own resources and hence develop coloring with yellowing of the sun leaves, but how you get there is completely irrelevant.
Whether you overfeed your girls and flush the hell out of them during the most productive time in it's flowering cycle OR you carefully dose your soil ammendments and not overdo the organic ferts or guanos it's totally up to you.
I totally respect CC and Prostele for that matter but that advice sounds so general it can't be wrong.....
It's easier to know what your shooting for and balance feedings.
My canadian homegrown goes toe to toe with any weed from any country.
Qc was the home of Heaven's Stairway before it all came down.

i'm probably the most inexperienced in this out of anyone here... if you grow 100% organics.. you should still probably flush for a week.. imo..but it mostlikely wont burn black ash if you don't.... i'm not talking about pure blend pro or most foxfarm stuff either.

Thanks for the valuable info there Protostele, makes some interesting reading & u
didn't even bad mouth anybody or tell them that "these guys dont no shit"
There is a vast diference between watering with plain water for the last 2-3 weeks of flowering & doing a complete flush. Because soil retains so much in the way of nutrients your herb shouldn't really need any more nutes in the last few weeks.
That is vastly different to doing a full flush which when done properly it is recomended to pump thru 3 times the pots volume in water. In my grows i use 30L posts - that would mean running 90L of water thru each pot! In my setup that would mean 270L of water! 20L of water added to my 30L pots has my top dressing perlite floating for half an hour! The idea of running anymore water than that thru my pots is frankly IMO just insane!
The idea of flushing my plants at just 4 -5 weeks into flowering & therefore effectively starving them when they are going into their final bulking up stage is beyond foolish. Anyone who does this is going to see some major Mag, P & K defencies amongst others. You're not just going to have yellowing shade leaves but dry, curled & dead leaves all over the plant, especally around the bud sites which makes pruning & manicuring a messy job & ugly buds. It will also leave u with skinny open airy buds. While the plants can store a fair amount of nutes in their cells, they can't store 4 weeks worth.
Certainlly nitrogen should be stoped at around 4 weeks into flowering, the plant just doesn't really need any more. The stretching should have stopped by this time & they'll be craving P,K & mag - really not the time to starve them.
I normally stop feeding around 2 weeks before harvest & switch to straight water but i've also fed them right up to harvest as well as stopping feeding at around 4 weeks before harvest (not on purpose, sometimes guests can be too nosy) & i have yet to see this "black ash" or harsh taste. But them all my nutes are 100% organic - certified.

LOL. The topic of flushing or not to flush does bring out the "passion" in people at times. As one of those post Feb 06 members however, I want to show my appreciation to the site by contributing in a civil mannner.
Suby is quite right imo about not overfeeding your plants so you don't have to flush the hell out of them. I started indoor growing with a hydroponic system and chemical nutrients at levels recommended by the hydro shop and they were way overfed. Flushing with clearing solution and then pure water for two weeks worked a lot better than the time I only gave them 5 days, but it still wasn't the best burning or tasting bud.
I think the hydro store recommendations are geared toward max yield but even my ppm readings of ~1500 were a lot less than what I was reading on OG for what others were pumping into their plants. If I ever try hydro again I will go for a lot lower level at maybe half what I was running and see how that goes.
Suby, I think Jason King was referring to commerical pot in Amsterdam and Canada when he gave his opinion. I have read complaints that we keep our good pot here and export our swag down south.
I have since turned to a soilless mix and was using all organics previous to this current grow but I noticed in one of my earlier crops that I think I fed too long that I got black ash, harshness on the throat and a tendency for the joint to go out.
I also grow in a bin that holds 50 gallons and reuse my mix as detailed by the Three Little Birds. I don't truly flush as some recommend with several times the volume of water. It just isn't practical for me either. I have a drain in the bin but it is low to the floor and I can only collect runoff in a shallow pan. All my water is either RO obtained from the SuperStore or rain off the steel roof and I was away during our recent rain and couldn't collect any.
I now curtail feeding my plants any extra nutrients like pure blend bloom when I water and let the plants use up what is in the mix. I had a soil analysis done at the end of my last grow, which was my best tasting and burning yet, and the nitrogen was down to 31 ppm and the normal range is given at 60-175 ppm. This was after 3 weeks of plain watering too. The plants were not starving as there was always some available, but not in excessive amounts.
I alluded earlier that this current crop isn't all organic. I have used a bottle of micro (pure with no NPK) left over from my hydro days. After adding fresh coco, wormcastings and an organic blend of Gaia Green 4-8-4, I had a new analysis done after it had worked for a month or so and the results surprised me. The nitrogen was at 397 ppm (normal 60-175), phorphorus 2.82 (normal 5-15), potassium 1358.33 (normal 75-200). Calcium was 570 (normal 75-200), magnesium 107(normal 40-75)
The micro nutrients were all well below normal with iron .11 ppm (.5-3), manganese .03 (.5-3),copper .05 (.1-.5),zinc .03 (.5-2)and boron .05 (.1-.5)
I had already planted a week before the analysis arrived, so I gave the bin a good watering and checked the runoff. The ppm was over 5000! It was impossible to flush out the mix properly so I just kept things well watered and they have done very nicely with no sign of burn or nutrient lockout. I have used Liquid bat guano 0-2-0 to bring up the phosphorus and the hydro micro for the rest, but I use weak solutions and now at day 40 flowering I have stopped giving them anything but water.
I am keeping my fingers crossed that the excessive nutrient levels early on doesn't affect the smoke much. The plants (Subcool's Black Russian) look nice and have well formed buds.
Does anyone know if the "normal" figures given by the lab for general greenhouse use, match that preferred by cannabis?

Congrats on the soil recycling, you definately understand why we flush and how to maintain soil integrity over more than one grow so my hat goes off to you.
I wasn't aware he was comenting on commercial bud, i should have guessed but then again I haven't bought weed in like 5 years.
I've stop supplementing with PBPro just to see if I could cocktail it myself, I just use guanos and LiquidKarma and fatten up the flowering mix, I reuse my soil outdoors for lack of space to recycle indoors, a wormbin is my next project.
Dare I ask which tasted better to you, the flushed hydro or soil bud?
I'm sure you'll love the BlackRussian, I have been itching for that strain for years, let me know how it coloured.
Peace

To me the soil (soilless really) is the better tasting. Might be a case of comparing apples with oranges in my situation as I used mostly chemicals in the hydro and probably at an excessive rate and now I use organics and attempt to not overfeed, though this current grow started off with high levels.
I started four Black Russians and got two females. There is purple in the leaves but one pheno is definitely more purple than the other. The colour was more purple around day 21 of flowering and now at day 40 the shade is less purple and more of a black colour.
My temperatures at night have been dipping to ~17C or less for most of the grow since we have not been running the wood furnace much this spring. I am wondering if my cool night temps brought out the purple too soon. I have mothers of both phenos now so I will be able to compare later crops grown under different conditions.
Just uploaded my first picture to the gallery. This bud is from the more purple plant.

purple pheno plants tend to suck the Mag & K but especally the Mag. I've noticed the purple colouring start to fade in some of my purple girls just before a mag def becomes visable in the leaves.
Most purple pheno plants show their colour much better in the cold weather however some strains aren't dependant on cool temps like the lightstrom.
