When to stop Nitrogen?

[MR.Grass]

Ok im going into my fifth week of flowering White Russian,using fox farm nutes.When should i lay off the Nitrogen?

 

[jondamon]

Now.

You should already have been using the bloom nutrients. too much N during flowering will cause your plant to still want to veg instead of putting her energy into flower production.

wrong info! listen to me and u will be ok - right so ur in week 5 floweriing ok - during the whole of the flowering phase your plants till need a little N (just to keep big fan leaves etc) to stay green and provide the buds with energy from the light - continue to use all ur bloom nutes and use VEG nutes (K) up untill the last 2 weeks of flowering! this does ur plants no harm wot so ever. It keeps the big fan leaves green and healthy and after all this s where u plants send all the energy an growth from the light - peace

USE THE VEG NUTES AT 1/4 STRENGTH WHEN U GET INTO FLOWERRING UP UNTIL THE LAST 2 WEEKS OF FLOWERING!

ok cool,im using the whole line up of nutes from fox farm,and following the grow chart,i have read to continue with the grow big just not when to stop.thanks

 

[MR.Grass]

they are doing awesome feeding at 780 ppms u think i should give more?

Personally I think the FF lacks N. I didn't like how yellow my leaves were coming out when I started the flower nutes. I added the grow big back to their schedule at 2tsp/gal and they look better.

The answer to your question is never

 

[jondamon]

bloom nutes still contain N . my point was that too much N goes towards more foliage when you want your plant to concentrate on flowering .

so my answer is not wrong

N is required for certain plant functions and at the end N is required for proper curing, High P bloom nutes are wrong period, and it is the dark period that triggers flowering not N or P or K for that matter sorry but your statement is wrong

 

[jondamon]

so what your saying riddle is that we only ever need to buy grow nutes and never bloom nutes?

im talking bloom not pk boosters.

Doesn't fox farm nutes have a proper mixture for this time of flowering? That's supposed to be good stuff right? I know the liquid I use tells you on the bottle what, and how much to use during different stages of plant growth. That way I don't frig up!

 

[riddleme]

pretty much, that is true

best NPK ratio is 3-1-2 for veg and 2-1-3 for flower this has pretty much been proven and I have posted this info in my threads (with back up from edu, botany, biology and real garden sites)

I just posted a ditty on harvesting explaining why N is needed for proper curing, it fuels the process that converts the plants sugars

 

[whiteflour]

I'm not sure where I stand on the PK thing yet. This is the first time I've used "cannabis" nutes, so we'll see. But I do believe most peoples grows on here I've seen drop the N way too early, and looking at the growth I got from FF I understand why. It took me one fertilizing to tell something wasn't right when all the new leaf foilage was yellow-green.

There's nothing wrong with some leaf on the plant in flower, in fact it's beneficial. The idea isn't really to overload the plant with N as foilage production on it's on is going to decrease, but you do want to make sure any new foilage is as healthy as possible, and the mature foilage maintains it's green.

yes i understand that that i was talking about the use of bloom nutes in my response. bloom nutes have lower N but still have N in them. i told the OP that he should be using his bloom nutes because they dont contain as much N.

i just dont get why you think im wrong, its not like i told him to go buy some BIG BUD LIQUID or anything. i just told him to use his bloom.

What was wrong was that more N would cause veg growth, test have been done that show that what the plant actually uses is N and K with just a little P and the notion that high P is needed is based on outside grows not inside because outside P is more easily leeched out of the soil so more is put in to compensate for this, in container gardening very little P is needed as it is not leeched out as easily

and as long as the photoperiod is 12/12 N will be used by the plant to make buds, not veg

and I wasn't hatin, just trying to point out the truth for you and everyone else

 

[jondamon]

alot of the research i have done must be wrong. ive even done research about crop steering using higher and lower EC to steer a crop . maybe im too brain fried and crossing shit ive learned lol

thnx for putting me straight

Which brings back the age old question; Is there anything that will get a plant into, and done with flowering faster? Fewer hrs of light is not the answer Im looking for.

 

[whiteflour]

My belief is no. Maturity is time dependent. Providing the correct nutes will only provide sustainment or improved growth rates.

there is a thread in the advanced forum where they are talking about a 20/12 cycle which creates a 32 hour day

and another where they are layering branches to speed up plant vigor

not gonna get your answer in the newbie forum

"Nitrogen is an important component of many important structural, genetic and metabolic compounds in plant cells. It is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e. photosynthesis). It is also a major component of amino acids, the building blocks of proteins. Some proteins act as structural units in plant cells while others act as enzymes, making possible many of the biochemical reactions on which life is based. Nitrogen is a component of energy-transfer compounds, such as ATP (adenosine triphosphate) which allow cells to conserve and use the energy released in metabolism. Finally, nitrogen is a significant component of nucleic acids such as DNA, the genetic material that allows cells (and eventually whole plants) to grow and reproduce."

Nitrogen is definitely still needed just not as much as the veg phase! Im at week 5 flowering myself and am using GH nutrients. Their formula is 2.5 mL Grow, 7 mL Micro, and 18mL Bloom. It is recommended that flowering plants that finish later than 6 weeks stick to this formula until a few weeks before flushing... After this, move into a nutrient formula that has no Grow as the bloom nutrients still contain nitrogen (and the Micro to). Remember that the special molecule that we are trying to create has no nitrogen and that the final energy stores in the plant (during flushing) are being used to create it!
