what are the benefits of no nitrogen mid-late flowering?

[dizzlekush]

whoever negrepped me for my input is real clown.... curious why? show yourself

It was me.

too much nitro with give you less trichomes too
instead of the neg rep maybe explain why u disagree

Because everything you've said about nitrogen has been total hogwash

please provide any proof that anything you say is correct. Some studies on trichome density perhaps? They're rather common, if what you say is true it should be easy to find. Is it NH2, NO3 or NH4 that does this? Uh oh, whats this?

Cannabinoid Profile and Elemental Uptake of Cannabis sativa L. as Influenced by Soil Characteristics

(From results)
...
Plant N, previously shown negatively correlated with soil Mg (Table 4),was positively correlated with delta-9THC (Table 7). Haney and Kutscheid (1973) reported positive correlation of total soil N with delta-9THC levels in wild C. sativa in Illinois....Plant N was positively correlated with the CBD/ CBN ratio (Table 8). Plant N was also positively correlated with delta-9THC(Table 7),...

Responses of Greenhouse-grown Cannabis sativa L. to Nitrogen, Phosphorus, and Potassium
C.B. Coffman & W.A. Genters

(From results)
...
There were no signficant growth or cannabinoid responses to varied rates of applied N and K, although maximum plant growth and delta-9THC yields were associated with soil P in conjunction with high N or moderate to high K levels in the soil....

That's 3 studies right there that all showed that high N was necessary for high THC

Ive done 2 side by side grows now comparing low N and high N fertigation methods in bloom. Both times the high N groups yielded significantly more, and had the same potency as the lower N groups.

speaking from my experience, not someone elses

been there done that

dizzle
I looked on your page for shots of dank you grew , couldnt find any

 

[TribalSeeds]

that is a nice canopy

Id actually recommend toning it back a bit.

More and more growers are coming to realize that keeping it green till harvest is key to good yields ,
to much nutrients and your plants get burnt = plant stress
to little nutrients and plant shows signs of def = plant stress yields diminish
Stop thinking that a plant needs to yellow that's the life cycle bla bla bla , horse shit its maintaining all key micro and macro till plants is ready to harvest
when growing out door there are other elements that are at work here like colder night temps etc causing leaf coloring etc in indoor growing we are luckier we can keep temps to near perfect controlled climates

Lol.. I got neg rep'd 6 times..... I love it!!!!!!!

For proper complete production N should be used for entire growth. Pure and simple. This dropping of N after flowering is bro-science. The yellowing that does happens naturally is some strains is called senescence.

To be fair... I negged your first post because this thread is about 6/9. To be clear... The OP is looking for experience with the recipe indoors w/coco.
I kind of agree with you on N though. But again, this isnt an organic grow and hes wondering about chem nutes and flushing

 

[dizzlekush]

See now i can say whoever neg repped me is a clown since they voted that the only bit of science in this thread, which concluded the same thing from three separate studies, was unhelpful. Only a clown cant find science helpful.

Thanks whoever you are for reminding me why i dont help growers on forums anymore.

I failed to see that upon first read.......

Don't let the village idiots stop you from helping those that accept and apprieaciate the help. When I see them idiotic posts, I go at em and be blunt. Misinformation runs in these circles so deep it's pathetic.

Ive always thought that a proper soil mix was suppose to be fading out by the end. But Ive never grown in soil. Ive just read some of the recipes

I try and cut out N by around the 7th week of flower. I use foxfarm trio+solubles w/ocean forest. I noticed when giving full doses to the end up to the point to where i flush, the end product taste much more "green." Also when they hit the jars for curing they take much longer for the chlorophyll to break down, and nugs stay greener in the jar for much longer instead of the golden green color that they should be.Lastly the smoke is much more abrasive, i like my smoke to be as smooth as possible

I've been using this 6/9 formula for years. I adjust the formula depending on how my plants eat. Am I using co2 or not will also change the formula for me. I stay at the same breakdown. 1 part micro to 1.5 parts bloom. It does very well for me.

What I don't do is cut out the nitrogen that early unless the strain that I'm growing warrents it. It also depends on my medium. For example if I'm growing in soil I cut out the nitrogen earlier than hydroton because soil will store some nutrients when you feed. My main goal is to keep the plants healthy and get them yellow at the very end. By that I mean that I want the plants to yellow the last 5 days or so. If my plants start yellowing 2 weeks before harvest, then yields will go down. I don't over feed my plants and my plants are very flavorful. If I'm growing hydroponically with a heavy feeder, I can cut my nitrogen for the last 5 days to get the yellow that I want. There's no set formula for growing. The strain will affect how your plants eat. Your environment will affect how your plants eat. Data is key to finding out how your plants feed under those specific environmental constants. Taking out your nitrogen too early will decrease your yields as well as other factors depending on strain.

Out of curiosity...all of you people who cut N at some point in flowering, are you removing all nutrients or just the nitrogen?

I've been using 0-6-9 for years now in coco, maybe 20 different strains. I usually start cutting the micro out around week 6 or 7 on an 8-9 week strain (with 1 week flush after that). Usually, there's not a green leaf in the room when things are done. I like cutting the nitrogen out, it definitely makes my nugs lighter in color, and MUCH smoother and tastier compared to super dark green nugs.
I believe that after mid-flower, the leaves have basically done their thing. The plant changes modes, and the last bit of flowering the energy comes more from energy stored within the plant.
I have completely de-leafed plants at week 6 that finished fine, but I think in late flower, the leaves are used by the plant more for transpiration than food making, so the nitrogen isn't as necessary.
On an 8-9 week strain, at week 6 or 7 I've usually cut the micro out completely, finish using 0-0-10 with some addatives.
I usually still use a bit of Cal-Mag, so there's a little nitrogen still in the mix, but finishing without the N, with all yellow leaves, definitely works for me. Yields are the best ever, and getting better, usually over 1.5lbs per 1k light, no C02.

As mentioned though, it does come down to reading the plants. Too yellow early on not so good, super green late in flower always made for harsh smoke for me, so I cut the nitrogen out when I feel necessary.

I cut everything at the same time. If I was to give an average, it would look something like this:

Soil 5 gallon containers - cut everything 2 weeks before chop.

RDWC and aeroponics using hydroton - Cut out 5-10 days before chop.

The other thing I do that I didnt state here is I lower the nutes the week before I cut the nutes 20% or so. I never feed more than 2EC but usually stay around 1.6EC and those are my heavy feeders. This is with CO2. Without CO2 the plants need less. I use to blast my plants with more nutes but I noticed that when I took the nutes down, I got flavor and yield increased. My primary goal is to give the plants just enough that it seems too little but its not. I can double my nutes without burning the plants with my good feeders and the plants look just as healthy as my lower feeds. The only difference is that my lower feeds produce more yield as well as crazy flavor.

 

[supermanlives]

thank god i grow for quality not quantity.pupmping nutes till the chop will never get ya the primo aaa quality. fuck yield . i have experimented several times. whatever works for you .

 

[spiralofeyes]

Amen!

I've seen growers talk about how the 'autumn look' is the ideal look for cannabis at harvest. Cannabis is an annual, perennials get the 'autumn look' to them because of certain environmental signals telling them to prepare for winter. My annuals don't turn colors when the season changes, they just die.

Nitrogen is probably the most underrated element when it comes to indoor growing which is confusing to me because cannabis is a leafy, flowering plant. Bloom boosters aren't going to maintain healthy leaves and without foliage, you've got no yield.

What are the benefits of no nitrogen mid-late flowering? Less trimming due to the fact that you've yielded less and lost all your leaves during the life cycle. I'd go as far to say that potency from a deficient plant is lower than that of a plant that was grown properly. 'Grown properly' to me means you've met the nutritional needs of your plant at all times allowing it to full express itself.

To elaborate a bit, the overall nutritional needs of your plants is a lot lower near harvest than that of any other time during the flowering period. Feed accordingly by reading your plants. My plants talk to me, yours will too if you know how to listen.

^^^^^^^^^^ Exactly as home brewer mentions until growers realize the difference between a annual and perennials there grows will become better throughout
Nitrogen is needed in all stages of growth and also in bloom but not as much but still very important
And that makes a difference between a good grower and one that reads more posts and follow other idiotic idea's ???
Under standing what a plant needs and fighting to keep them leafs green is a guarnteed WIN WIN and that is what makes a GURU grower

Just go look at some legend growers for one Heath look at his plant near harvest is is defoiled leafs falling off ???? No its green and happy
