The True Cycle of a Cannabis Plant and Yellowing Leaves

Reason I stumbled upon this thread is...my plants are yellowing. The buds are still growing and green. I did fix a PH problem this week as it was at 5-5.5 ...now it is 6.5 so it may just be a cal mag lockout from the low PH...sorry bout the light being on...added couple without light on

LOL, So he apparently has been growing for 7-8 yrs and this is what his current plants look like. He quit posting here because he got called out on his BS. Green thumb? I don't think so:o

I have the luxury of experimenting with techniques, which I have stated, but that goes way over your head

I don't really give a flying F what you negative guys say

clearly you have nothing better to do

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.

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. This also gives the grower confidence in the plants development and the time when she is really ready for Harvest.

Just some thoughts of mine...peace GM
Tric colour is strain dependent. Go by density,receding hairs and trics, these 3 are your safest bwt.feed to the end whwn ahe most needs it

One of those techniques is called nute burn, numba 1 US at this technique.

Just wanted to bump this thread.
I grow outdoors naturally, and I love it when my shade leaves turn yellow, as I know it's nearly ready for harvest.

Also it blends in with the nature I have around me, for extra camouflage, and we use the yellow leaves as "tobacco" for rolling cigarettes as we don't smoke tobacco ( anymore ).It's still nice to have a smoke in the morning without being totally stoned for 2 hours, so a yellow leaf roll-up is quite pleasant.

I find the outdoor grow with yellowing leaves tastes "better"... it certainly tastes different to my indoor grows where I keep the leaves green til the end and use ferts.
"Stronger" is also important, and I have my own strain of seeds now, after a few years of growing, and I notice minimal difference in strength between indoor/chemical/green buds and outdoor/organic/yellow bud, just that the taste and the smell are different.

The outdoor smells more "organic", no "green" smell whilst smoking...the indoor the opposite.

I'm happy with both ways, as the laws still dictate that we have to grow indoors in some places, sadly, but I think yellowing for me feels more "normal".

From everything I've read over the years none of the OP fade reasoning's stack up.

How I understand it is this.

In the past people thought they had to reduce N by drastic amounts and increase P by drastic amounts indoor. People still think that now. What you end up with is a plant that will begin to fade and yellow out mid flower and on. It's not the plant naturally dying.. just getting starved of N on top of bad ratio lock outs > reduced yield.

Then I see people who like to flush or drastically reduce over all fert count in the last two weeks or so. The plant is not magically entering it's last days.. it's just being starved during it's last days.

Enter some logic into this. The soil out door does not just stop providing ample levels of any nutrient (if good soil ofc) the plant simply stops asking for certain amounts of w/e. Microbe signals play a role in that.

If you put a low ppm yet ample amount of each nutrient into a indoor container + microbes the plant will choose what it wants by itself. Some lower to mid leaves may drop due to light shading, a slight lack of a certain nutrient or are generally not needed by the plant any more. High amounts of top leaves that yellow IMO is a sign of having lights too close and over working leaves or the nutrient levels/ratios are off.

For me a indoor plant can be fed around 8-900 ppm of a balanced ratio until the end. Most lower leaves will drop, some mid leaves will drop but most top leaves should be in tact. Again, my opinion. Feeding that much may well be a waste in the last weeks, 600 may be better.

People who say out door tastes better than indoor are likely correct on the whole but that has jack shit to do with ''natural fades'' and everything to do with a supreme spectrum and microbial diversity. But you can resemble that indoor with the correct lighting and use of microbes. It likely is not as good but you also have to factor in coco/tupa and the yield increase it brings. I think even hydro users can apply microbes these days? although I can't imagine them to be as diverse.

Ofc outdoor fully organic growing is the moral high ground regardless of yields or w/e else.

Can a plant be ready to harvest at the end of it's 7th week of flower?

I have 3 strains grow in a tent and 2 of them now have yellow leaves and the Ti-combs are clouding over. Everything is pointing to the fact that they are very close to being ready but it is very early time wise.

The stains are : Tangine and Kosher Kosh
Lights : 2- 300 w LEDs about 18" from tops
Temp: 79* with 46% humidity
In Soil with regular feeds on Nuts
Flowering for 46 days

Should I let them go another week or are they ready now?
A good rule of thumb. If you think its ready, wait one more week.

Very few will be done in 7 weeks. Very few are even true 8 week strains.

I generally expect at least 10 weeks flower. I prefer sativas and sativa crosses.

Pure indicas and indica dominant strains will be the one that can finish as fast as 8.

Every strain I've grown that claimed 8 weeks was never done in that time. Not for my taste anyways. That may have been the very start of the harvest window.
