Organic nutes no Senescence ?

[somerandom]

I'm wondering if it's normal for a plant to seemingly not go through senescence using organic nutes .

I'm doing a test with organic nutes and a small vert tent neither of which i have done before and the plants just don't want to seem to finish. Very little yellowing of the leaves /dead leaves and the ones that appear to be dying don't want to let go with my usually tug .

I normally go about 73 days from flip depending , and sometimes a little longer . The trichs are about 50%-60% milky with no amber and it's day 83 for the one i have been checking The environment is far from perfect but what the hell ? lol .

sounds like a long flowering sativa

Organics when done right should finish green. No need to flush when excessive salts are not present.

 

[FatherEarth]

salts are still present when using organics especially when the soil gets dry. ...


To answer your question... if your plants are getting all macro, micro and trace elements & nutrients, yes senescence can be delayed considerably. Its been said that you should not to worry, you can still harvest at the normal finish time even with clear trichs the potency is still there and that they will cloud up with a cure... Bud will look immature but the potency and the terpenes should be off the charts...Maybe I can get someone with first hand experience over here to explain it a bit better...

Milkyjoe is the guy to talk to about this topic...

you cant flush a plant, only the medium in which it grows. What you want is the plant to consume its reserves, especially sugars. Im in the line of thinking that if you starve a plant the last weeks of its life "flushing" you are missing out on the best part of flowering and keeping the plant from being all it can be. Packing on essential oils and terpenes in the last two weeks is important. If your nutes are in the soil already like as with soil amendments..Id let them reach harvest date then start locking out nutrients with a PH swing of the water. Making it so the plant cannot uptake anything from the soil. After harvest add some beneficial microbes like spectrum extra, then re amend and reuse...

FWIW,

what direction would you swing the ph?

 

[bigshrimp]

Some plants don't yellow without starving them, on the flip side i have had plants that would yellow very early and continue to pack nugget but refuse to green up. If the plant is healthy and budding don't worry about how ugly it finishes.

You'll get a better idea of what happening as you run your cuts a few times.

I completely disagree, senescence is a natural process as the plant prepares to die. MJ plants are not meant to live forever, they have a very clear and defined life cycles, harvest time is when in nature the seeds should be ripe and mother plant prepares to die and decompose for the plant to become food for future plants.

Also, salts are present, just because you don't grow with chems does not mean there is no salts. Minerals = salts.

Now I will not comment on to flush or not because the term is so often abused it's not worth opening that can of worms.


All of my plants show senescence with organics to varying degreees, and that's the way I like it. No need to smoke all of that chlorophyll. So many growers both chem and organic think plants should be full green at harvest time, yeah they may look pretty but that doesn't make it the right way to do it.

Hiding haze,

Plants do reach an age limit and natural senescence begins. We are finding using the AEA products and Tainio microbes plants do not reach the natural limit like they used to. I mean weeks past normal harvest no yellowing, all white pistils and still stacking buds and not slowing down. A person experiencing this phenomenon postulated that we don't truly know the full lifespan potential of cannabis. Especially those with equatorial origins. ..

i also disagree that organic plants should finish green. Thats not to say its a terrible thing, it kind of depends how green we are talking. I like mine to fade as much as possible and usually i can achieve this.

senescence depends on genetics, flowering time and nutrient abundance amongst other things. as said above some are very willing to fade out of their own accord and some need a push by ensuring that nutrients, especially nitrogen, run short as harvest time approaches. if the OP has never grown the strain before then he has no frame of reference for what is normal.
its a fairly common phenomena for some strains to be reluctanct to fade if they are in a rich organic soil.

I say that a green plant harvested green can be cured properly and still smoke great. A yellowed plant simply makes it easier although I'll bet the hog the greener fully fed plant will test higher in the lab analysis in potency and terpenes, not to mention the yield ... Dial in your drying curing methods ftw. All I'm going to say is..We are approaching a shift in knowledge about what we think we know about producing truly healthy cannabis and plants in general. The very start of an upswing that will change agriculture as we know it today.
Fasten your seat belts and open your mind.

[VerdantGreen]

FE you may be right up to a point about potency etc, like i said green can be ok it just depends how green we are talking about.

there are several environmental triggers that 'flip the switch' to senescnence. Root restriction, starvation, temperatures, light cycle can all contribute... along with the genetic pre-disposition.

it will be interesting for sure how science and agricultural advancement will change our attitudes and practices. I have a theory that triggering senescence may actually help yields and potency because it begins the process of re-cycling nutrients already stored within the plant material - at a time when the roots are decreasing in their efficiency for nutrient uptake.

I thought it was interesting when my last crop of only blue dream clones that I jam packed under and around the lights only yellowed directly under the lights. The ones around the outside stayed green even at harvest. They were in a very light orangic mix with all the usuals but it was 1\4 the strength as I usually mix my soil at.

Now that they are in the jars all mixed up I can still tell which ones were the green ones, slightly more harsh of a smoke.

So did the ones on the outside not burn through the rest of the chlorophyll like the ones in the middle because of the light degrading it? Or is more like they are using more energy under the lights so they have to eat more?

 

[VerdantGreen]

the more light energy a plant recieves, the more nutrients it can and will use.

did you compare the yeild? from the yellow ones in the sweet spot under the light and the green ones round the outside?

[Corpsey]

That's what I was thinking, but I never saw it so clear because usually I have different plants and I would just attribute it to them wanting different things from a 1 size fits all soil mix.

Yeah obviously the ones directly under the lights were a bit bigger and thicker.

 

[Weird]

in nature microbial activity is effected by the weather, as it gets cool, microbiology slows and effects the plant accordingly.

 

[FatherEarth]

Ethylene gas produced by plants signals other plants to begin senescence as well.

If you didn't take your blue dream 11.5 weeks it wasn't ready. Well worth the wait too yield nearly doubles from the 8 week mark..

 

[FatherEarth]

I think delaying senescence would be more productive. Keeping the plant producing flowers in high gear, longer will obviously be beneficial to our interests.

 

[Corpsey]

Never taken the dream to 11.5, I thought it would dull it out and make me sleepy. But I have one in flower now that I will take you up on an experiment, I'll try to bring it to 11.5

And are you saying all plants should be taken longer? Not just BD.

Only so much photosynthesis can occur without altering certain perametersoutside of natures usual limits. Like boosting co2 levels increases plants nutrient uptake and using products like photomag to increase the plants ability to photosynthesize. More photosynthesis ftw. Just giving more light is only good to a point. Gavitas are a good place to start
