Benefits of N Deficiency?

[Where'sMyBud?]

Ok, so I have never had a plant yet have its leaves turn yellow towards end of flower do to N deficiency - however, I see a lot of pics of people's plants that do...

Is there anything beneficial about trying to starve a plant of N midway through flower so that by the end of bloom it will be a yellow mess? How much N is the plant really using halfway through flower - how much does it need to jsut stay alive?

Also - random question...

When growing in the outdoors - or a meat freezer, when plants begin to turn brilliant shades of purple & red, what is the chemical compund name of that (ie chloryphil is to green as _____ is to purple)?

I don't think there is a benefit to letting the leaves go yellow. It may actually not be good. Anthocyanin is the purple pigment. In fall, sometimes chlorophyll will break down to reveal this pigment.

There is a benefit to to giving less N nutes towards the end of flowering. You won't have such a strong green [clorophyll] taste in the end product.

If you dont pull back the N content in flowering you will stunt flowering potential.

N might be good for leaves but its not for buds.

Leaves=energy; Less nitrogen in flower but not no nitrogen

in the last few weeks of flower you want them to go N def so that you get a better taste due to lower levels of chlorophyll in the leaves

Is the taste really better because of the chlorophyll?

Take care

agnes,

Buds definately taste less "green" or "leafy" or "grassy" (not the good kind ) when chlorophyll has been degraded in the plant matter. That's why water curing works so well...

So in theory, guys, the plant should use up nearly all of the available N in the growing medium by the end of flower, right? So if I don't feed it any N after veg, I should expect to see yellowing of leaves for the most part?

Yes, you should expect to see yellowing of the leaves. I would use an organic carbohydrate synthesizer like Sweet made by Botanicare. This will replace the important carbohydrates, organic acids, vitamins, amino acids, enzymes, nucleic acids, and hormones that were once produces by N. It also had secondary and trace elements. You can look up more about it at www.americanagritech.com

I have yellowing in my blockhead an AK pheno's but now that I use grow big for a full 3-4 weeks into 12/12 my plants are much better in the end,I dont think it delays or stunts flowering as much as it enhances healthy veg growth resulting in better plants in my case,the stretch is a veg phase anyway.I used to go straight into tiger bloom when I switched to 12/12,the results I get using nitrogen longer has definately been beneficial

supposed to be good for taste. Yellow leaves are also from switching to bloom ferts to early. Here's some yeller.

I also used to get excessive yellowing during flower because I didnt use dolomite lime in my mix and the soil ph would drop below 6.

It takes time to learn a strain and not cut the nitrogen off too soon. But stop feeding nitrogen so that by the time ripening is done the big leaves have yellowed and consumed themselves. You will get a much smoother smoke with a nice light colored ash that shows its burning clean the ferts are all flushed out. Its the purpose of flushing really . Once you start the clear water flush the sunleaves should yellow soon afterwards and the plant should consume all extra ferts left. Leaving you with very tastey clean burning buds You dont want it to be a deficiency but you do want all the nitrogen and other ferts consumed by the time you harvest. Means you really have to learn your strain.

I grow in soil and never see a need to flush,I use fox farm tiger bloom to the end and never get any taste but the kindest of kind,I'll leave flushing to the hydro guys

Well if you never flush how would you know the difference?

I use Fox farm Tiger bloom as well, and when I do not flush well enough I can taste the difference for sure.

But you know us ladies we are finicky with some things. Guys tend to more laxed about how something tastes.

Buahahahahahahahahaha

I am stoned- um, I have noticed in my last harvest that a N def. seems to have made the flavor of the weed less "green" and nasty for freshly dried no cure buds (tasters).

Also, makes trimming go quickly.

 

[Guest]

I think thou may verily imagineth such a thing,if you be tastin sumthin I reckon it aint tiger bloom

 

[Babbabud]

I grow in soil but i even flush my outdoor plants right in the ground. Ive been smoking well over 40 years now and believe me if i dont flush even the soil weed i taste it.Course i use what we call soilless soil... the only ferts in it is what i add. I use nothing but botanicare and glacier water. After a good glacier water flush it taste like nothing but the best Heres what im talking about

Good info guys -

Krys0513 - I know what you mean...all my stoner chick friends totally have more adjectives for buds than guys, especially when they've tried stuff I've grown out before compared to street beasters.

Well, I honestly don't know how to plan for my leaves to turn yellow towards the end of flower since it is totally up to the individual plant to either use up all teh N in the soil or not. I will not be feeding my plants until probably week 3 of veg (out of 4) at the earliest and when that time comes it will not be a GROW fertilizer but rather FloraNova Bloom.

I don plan on using SWEET and Superthrive throughought veg and bloom however, but don't think that would be adding much N at all.
