how can N delay flowering?

[greekguy]

i have these plants in day 45 of 12/12
and they look that i have minimum a month to go,
i cannot find any orange pistils all are white and vigorously... (maybe 1 or 2 out of hundreds of buds...)

isint this strange?

could this have to do with nitrogen?
1 of the fertz i use -a chemical one, has 12-48-8 what do you think???

i know that i should be patient, but u didnt answer the q about N, could it have to do with delay of maturity???

The answer is : maybe IMO

What strain is it?

If it has a lot of sativa in it, Nitrogen will "encourage" the plant to keep on making new vegetative growth. The advice I got from good sativa growers is to cut them off Nitrogen a month or so before expected harvest date...which is what I did with the two haze hybrids I have going into weeks 11 and 12.

It would help to know what strain you are growing.

My Western Winds' pistils don't want to die down until around the 9-10th week...

I can't answer the N question. I came in because I'd never heard the question before and wanted to know myself.

Your baby looks like a Sativa to me. It's possible that you haven't even hit the halfway point. I'm trying THaze x Skunk and have been told to expect 120 days of flowering, maybe more.

Were they clones, or from seed--

Quite simply
N encourages veg growth
P and K encourage flowering

Yes excessive nitrogen can delay flowering. Nitrogen is responsible for lush, healthy growth. Once the plant is established and the photoperiod is changed, flowering plants direct their attention to the flowers. Nitrogen does not help the flowers to mature therefore very little is needed in the flower stage.

Unfortunately, more recent research has shown that feeding your plants too much nitrogen can lead to the delaying or outright stopping of blooming.

I wanted to know that myself, I jst recently heard that people are cutting nitrogen off completely about half way through budding, I'm going to try this nxt grow as my last crop did not "fill" out quite as much as I wanted and this might hav been because the N was telling the plant to keep growing instead of finishes its life cycle and getting ready to reproduce with big juicy buds.

its purepower plant from seed -nirvana

and as i said among other stuff i use my fertilizer is 12-48-8, +molasses
is the 12 in my fertilizer too much of a N?

 

[Guest]

I have to disagree that once the photoperiod is changed nitrogen should be discontinued,I've found the opposite to be true.The plants require more nitrogen during the first 3 weeks or so of 12/12 than at any time during the veg photoperiod.Veg growth intensifies during the start of the flowering photoperiod and nitrogen is sorely needed.How many "are yellow leaves at 30 days flower normal" threads do we need to figure that one out lol.

Those actual numbers do not mean too much, teh actual numbers are ratios
so your would be 3-12-2

where the PBP I use in flowering is 1.5-4-5.



you can see here there is nothing wrong with my ratio

If you want something that is a no brainer and very very easy to use, get yourself some PBP

Nitrogen should be used sparingly in flower but it should not be used in excess. I like to supplement N in flower until about the 3 week mark when the plant starts putting out flowers. Once flowers appear, then it is time to switch to a high pk fertilizer.

Greekguy.. thats strange about your PPPs. Ive grown her before and she was a fast finisher. Your ratio sounds ok but I would supplement some potassium for late flowering to push them along. Not sure that nitrogen is your problem here.

 

[greekguy]

dr dog- is pbl a strain? im a noob
and if not what strain that on ur pic? -how many days before harvest?

trichosaurus- isint 12-48-8 enough potassium??? i think it is, isint it? +my molasses have some in it also
as for ppp: i know that may sound stupid, but i'm beggining to believe that the delay has to do with my (future) massive buds. i believe that they have developed a "huge" root system that means to give some "huge" buds, i belive they will try their best.

 

[trichosaurus]

I really would give them some more potassium in the form of greensand or kelp. Molasses will add some more K but not enough with your ferts imo.
My PPPs were all mostly indica but one of them was much more sativa and she took 71 days. So I think you may be worrying too much on this. Your plants may go 70-85 days but you should be happy with the result.

PBP

You have officially stumped my band. Can someone name that tune for me?

I agree with that, most plants can double, some even triple in size in the first few weeks of flowering so they need A LOT of nitrogen... BUT like I said before, I've heard it should be discontinued (or very little used) after ur bout half way thru flowering (after week 4 of flowering on a 8 week finishing strain)... That is after ur plant has had its growth spurt (like all most all annuals do before flowering) and then has stopped growing up and out, so it can produce flowers.
... I wouldn't want to stop using nitrogen as soon as u flip to 12/12, but half way thru flowering definitely sounds safe, and makes a lot of sense.

Cheers all!

Reading labels can be enlightening...

Kool Bloom for example....

Here are the percents as follows....

2% ammoniacal nitrogen
45% phosphate
28% potassium
1% magnesium
1.5% sulfur

The micros are eliminated but not all nitrogen....

Ammoniacal nitrogen is needed for flowering processes....

 

[Guest]

A good point here: N may possibly DELAY flowering, but it doesn't PREVENT the plant from finishing flowering... In a natural environment a plant gets all its nutrients from the soil its growing in, which gets its nutrients from decomposing plant and animal matter/shite. So they always hav a certain amount of N-P and K, even if they are in a high N environment in the "wild" they still, begin flowering, and finish flowering, perhaps it is DELAYED slightly, but how much of a problem is this really?
(I hope this doesn't offend anyone, its not supposed to)

Cheers all.

 

[greekguy]

anybody offended form that its simply not worth thinking off

i agree dr. greenfinger, and what i want to add is this, could it be a that delaying flower some more-harvest time could mean BIGGER buds???? think about it...








thanks all of you for ur support in this
