in general the oldest leaves will die off, the pics will help though, you need full plant pics

DUDE?
Pics of the whole plant!
It's big impotante' that we see just where they are coming from.
Yet by simply looking at the leaves and what your saying.
You flipped and went to bloom and started to use the HIGH P bloom food right at the flip......
Too much P and too little N to start bloom.
Next time - Veg food for the first 2 weeks after the flip and for the 3rd week. Mix the veg and bloom 50:50 and at week 4 go 100% bloom nutes.
Fucking nutrient makers anyway....

plants are ignorant of weeks, they do as they do, list all the info you can

SW? "Time" and NPK values applied, in relation to where the plant is in it's life stage (time=days, days=weeks). Is very important as to how it reacts.
Your statement makes no sense.

the old leaves die off when they die off, without more info like the variables you listed to say otherwise that may be the case. And my statement is true, a plant has no concept of human time.

In attempting to understand the nature and cycle of a Cannabis plant, many conclude that knowing when a plant is finished is easily seen by watching all of the plants changes, which include; buds are no longer are swelling. Pistils have receded and have turned orange. Trichomes are cloudy/amber via a certain percentage. The strain's approximate flowering cycle in weeks. Leaves have/are turning yellow.
I believe a grower can see when a plant is ready by watching all of these "Signals", without even using a special scope to see when the Trics are a certain color, as Tric color can be seen with the naked eye. But the key is, making sure the plant is "Done".
Now, my real purpose of starting this Thread is to discuss the yellowing of leaves. I have talked to growers who feel that keeping fan leaves green all the way up to harvest is good and that yellowing of leaves at this stage is not the best for a maturing Cannabis plant.
I have done research on this subject, and the Cannabis plant in the wild can tell us something about how she will finish out her life during the final stages of maturity. In the wild, Cannabis will die at the end of Flowering, so the seeded buds can drop into the ground for the next natural grow. This seems logical as we all know that Cannabis didn't come from our Grow Room/Closet.
We also should consider that Cannabis in the wild does die, and the leaves will turn yellow during maturity. I've watched many growers, including myself, become nervous when leaves begin yellowing during the last 2-3 weeks of Flowering, wondering if we over/under-nuted. I'm not so sure that this "Stress" is warranted, as we are simply watching what Cannabis does in the wild, and, this is a firm signal that our plant is entering the final phase of Flowering. https://www.rollitup.org/t/the-true-cycle-of-a-cannabis-plant-and-yellowing-leaves.762408/
Trying to maintain green leaves all the way and into the final stage of Flowering seems to not only be unnatural, but also confuses a grower to when the plant is actually finished, as this is an important signal to know when to cut our plant(s) down. We also see some comparison to this when we watch Fall colors change our plants/trees during a certain time of year, letting us know the firm signal of a season via a plants color change.
It appears that a Cannabis plant will begin to digest the sugars/proteins/nutrients left over in the green leaves and this is what helps the buds develop fully in potency, size, and readiness."
I always turn to nature when I have questions with so many opinions. duplicate its natural outdoor environment as best as you can and your plant health will report as best as it can I think

I would give veg nutes until stretch is done. The stretch burns through a lot of N. I mean they can grow inches a day during that time.

This idea is not exactly true in how - why or when our plant is ready to be taken. We take the plant when "WE" are done. The plant can continue on far longer in it's attempts to reproduce before death. Ever notice in your garden, that your veggies don't yellow and die until they have reproduced. Maybe the few over the years that didn't. Stayed green longer trying.
Like someone said to me in another thread (and was right) Plants have no perception of "human" time. WE put a value of time on the plant to be done for our use. Other then basic stem fans, at lower levels. You should not really be getting coloring (pale yellowing) - unless the plant naturally colors with that expression......Purple, red, orange, yellows. Flat out pale yellow. Is not a natural color expression in mid weeks of bloom.
We (some of us that run longer then many) do get to a point where some minor extended coloring comes in (on a cpl of strains - some climbing yellowing by age). The color expression you suggest. Happens mostly to plants that have dropped their trich heads and have gone past prime harvest.
Another comparison you use above is TREE'S. See where I'm going to go with that yet? Not only are tree's not cannabis, they are perennial. The leaves color up and fall as part of it's ongoing life - not death. While the process is the same on some levels. It is most assuredly not on others. As cannabis colors out in late stages of life. It's a last ditch effort to put it's remaining energy into reproducing it's self.
As cannabis growers, we tend to feed in a way that enhances early death. Like a light bulb burning it's brightest before it dies. We feed them harder then they would ever be in nature. We have them "burning brightly". Anytime you have yellowing climbing up the plant from the base (other then "normal" stem leaf die off) at 4 weeks (or before). It's been feed too much P and the N was reduced , both too early...
Why does organic water only stay so green and lush so long? Why do organic run plants, run longer?
In synthetic use, we are basically "pushing" the plant as hard as we can to get the best yield we can (that's the focus as I see it around me).
I'm sorry Chemmy but, over the years of observation and experimentation. The lesson you give (well written too) I have to disagree with here.
In summation: Cannabis does not "yellow normally" at week 4 or 5 or even 6.....
The time to harvest, has nothing to do with the coloring of any leaves - I say your confusing people about harvesting!

While I do enjoy discussion and even disagreement you really need to read my whole posts for best results and less confusion, I see a pattern even.......
notice the quotation marks, source pasted in italics? I did not write this but surely the author will notice and he will appreciate your compliment.
if I allow a marijuana plant to continue past its proper ripeness the effects are ill for me and mine. yep I've kept them going for a long time and experienced dozens of these different trials with hundreds of strains. I have nothing but time to do these things for much of my life. I smoked them at every stage of 'done" before i decided what was the very best I could do. for me and mine is all.
my tomatoes will live on longer than I allow, so will my apples berries in fact all of my veggies will live past their harvest date if I allowed them too, but nope, I just dont like fermentation, I got a thing against it even unless in a fine wine/vodka/grog of course. I can taste it in late fruits, veggies, and yes weed. This is subjective and in no way authorizing a right way to do things, only my very best. I find it assuring to know there are many who have come to the same conclusions with similar trials.
again=If I feed heavy to the end my weed tastes like shit, no matter how long I allow it to grow or dry or ferment or jar or burp. I know it tastes better after a long jarring but not near as well as it does with a correct feeding and a three week open dry. to me. I dont wish to convince anyone to change their ways but I do hope new growers dont listen to old school ideals forever. I subscribe to what I learned in my life as a indoor and outdoor greenhouse, pond and soil grower. harvesting thousands of fish, rabbits, chickens fruits, veggies, and nuts its all about what seems natural to me. over feeding any of these items produces the same off flavors, like opening a bag of grass ferts. some cannot detect it likely but I can, dried, fermented or eaten I sense it. this becomes very important to me in my growing/harvesting cycles is all I aim to portray.

Plants have no perception of "human" time. While true, we share the big clock in the sky which we orbit. That clock rules our lives same as plants.

Yet WE put a "value" to the perception of time as WE understand it.
Minutes, Hours, days, etc, etc. Are simply human values given to explain "time" in our own minds!
"TIME" is simply a human concept!

The key words here. But we've been around that block before. So lets let that rest here.
The reply to the part in bold "and" the rest in general.
Remains the same!
I didn't go to the link, and the bold words are not really in quotation marks - one at the end and not the beginning. - Basis of my confusion. I was polite in the crediting, and in reality. the whole post deserves it.
Yes, I do flash over posts a bit to much..... I'll try to be more complete.....
