What do the leaves have to do with the bud? How would deficient leaves result in better tasting bud? I hope you know that the leaves turn yellow because the nutrient stores in those leaves are being transported to... the buds! The whole nitrogen leaching/flushing theory just doesn't make sense. Science tells us that flushing can serve no purpose other than washing out solubles from the medium. And "nitrogen leaching" is just a fancy term for malnutrition. Starving the plants will not result in better flavor. Supreme genetics, hung whole, dried cold/slow, trimmed afterword, handled gently, stored properly, cured precisely, etc... all this leads to maximum flavor/aroma when grown properly.

Flushing vs. Nitrogen Leaching
- Thread starter Mr. Terpz
- Start date
Maybe my throat is more sensitve then yours Mrterpz but heavy nutrient levels at the end of a grow leave a harsh, burning sensation in my throat. Same plant with even 1 week of half dosage nutrients burns smoother.
The plant uses and stores nutrition. We are not starving the plant, but forcing it to use its reserves so that it is a smoother smoke in the end.
If full expression of terps is what you are after you must use your nose to moniter the smell. There is a shift in aroma near the last 2 weeks. Sniff for it, flush and enjoy.

OFF TOPIC: Does cannabis continue to express trichome resins up until harvest time... or nearly so? If so, how does flushing (denying nutrition) affect trichome production days before harvest time? Something I observe every day with my plants outside is, they have a much more pungent fruitier sweeter fragrance early in the morning vs late in the afternoon after a hot day. It seems the sun burns off the terpenes and the plants replenish them at night... maybe I'm wrong. Anyway, I wonder if starving the plants affects trichome/terpene production.
I would say based on your statement, maybe the best time to harvest is at the end of a dark cycle, before the sun can attack any aromas.
I know when my lights turn off, the aroma level increases almost instantly. My DIY filter can handle most odor, but lights off and lights on it takes about 35 min to overcome.
We both know that trichomes continue the maturation also after the harvest. But i don't think that after the harvest also the production can change. But from the flush, this is something that i don't know.. If someone could answear then i would love to know why yes or no too 
There are a lot of kind of trichomes, also one kind that we can find on the leafs and steams also in the early vegetation, but they are very different. The plant produce them to maintain a good rh % in the microclima/micro atmosphere, and to help the plant with hydratation when the temperatures are high.. probably also against insects, bugs and uvb.
But If we think why those others trichomes that you/we are interested about are producted by the plant and which elements the plants need to produce them then i can just say that after the harvest no trichomes will be produced, but your question is different because i don't know which processes inside the plant are involved with the production. If at the base of the trichomes we could find some CaO f.ex. Then the plant could just pick what she needs in tap water or in the fan leaves.
With the things about the smell in the early morning, it could be that the humidity affect the smell or the trichomes, but i don't think that the sun could burn the terpenes, the temperature could surelly affect in a negative way.
I need to find some research.. it could be the same thing that i could notice in vegetation, the plants smell too in vegetation but it's another kind of smell of course. But in the dark and with light on the smell was more or less noticeable.. i don't remember when it was more or less noticeable..
What do you mean with great strategy that?

Please enlighten us all.
You can view however, mine is simple, find an awesome Organic grow and look and the leaf color. It is not a dark green but much lighter and almost see through. That is optimum feeding level. Any darker and it is storing energy. That is energy that needs to burn off.
My feed at the end is half strength for 2 weeks. Water to excess runoff each time and mulitple waterings. Never go without food, i just want those stores used up.
Organics will produce the best overall profile based on the simple fact you are not "forcing" the nutrients into the plants but allowing them to be available as needed at proper levels for healthy growth.
Atleast in my humble opinion.
Oxidation, Ok this is right! Death, i don't think so. When an amber trich tell me that thc has been oxidated into CBN: the terpene(cannabinoid) that give the couchlock effect, i could also say maturation or oxidation but that effect for me is everything but not something death.

I think that must be correct. So would harvesting when the trichomes begin to turn milky be a more optimal time than when they begin to turn amber?

I've been trying to do that so the plants make more and beefier trichomes but I'm just a newb with little success.

I waited to respond because I'm not sure what you mean. Are you asking me to GTFO?
I think he's saying to read threads that you have a basis in to expand your knowlage...
Imo some of the best burning flowers where broken off at day 50-60 when plant health is peak and they are eating well... some of the worst burn I ever saw was hydro with root rot and soil that was flushed for 3 weeks....
From my simple understanding nitrate nitrogen is the chunky no burn element... I use calcium sulphate to help tie up this nitrogen... but you want the other stuff in there or it won't burn either... I heard k helps shelf life as well and have had great luck "flushing" gypsum and molasses at .5-1 ec...
Also good to note that when you actually flush a medium like peat or coco, the lower the ec of the medium the more the ph will swing causing lock outs as well... fine lines... deficient plants tend to rot and go problematic imo...

Well, I'm here to learn all I can regarding all aspects of this endeavor. I'll try to avoid asking stupid questions in the future.
I'm reading this thread because I'll be ready to harvest in the next 2-4 weeks and I want to learn how to finish my plants for the best final product. My plants are showing definite signs of nitrogen deficiency and I'm trying to decide if I should modify my feeding regimen. I'm thinking of mixing a little tomato fertilizer and some DE and gypsum into the top of the soil so when it rains or when I water those will (hopefully) resolve deficiencies. I have no separate acidifiers or nitrogen at the moment.

Not knowing what you are working with, I say it is time for you to be master of your domain. You have a few ways to go, flush some, normal food others and whatever else you want to try. Hell even do 48 hrs darkness....
If this is your first grow, you need to be focusing on proper drying and curing of the bud. All the extra terps in the world wont cover hay smell....... Get this under your belt, try a few different finishing techniques and decide your favorite.
Being on a forum isnt about doing exactly what you are told by 100 people to do, its about reading those 100 suggestions and making your own informed decision.
I assure you, nobody on either side of this conversation is "wrong", we just all have our opinions of whats "best".
