Myth or Fact?

[flylowgethigh]

I have two plants with yellow leaves flowering in the same tent with plants that have green. They are drinking from the same reservoir. What is the suggestion for these?

Thank you for your posts. I agree there are reasons to prune and defoliate plants (e. g. Removal of dead stuff, airflow, etc.).

I am looking at the narrow question; “Do poorly lighted branches or yellow leaves waste a plant’s resources, and does removal redirect a plant’s energy?”

My personal SWAG is no. I believe a plant directs its resources where they are most likely to aid in reproduction. It will do this in the most efficient manner available.

This would explain nutrient poor, chlorotic undergrowth. The plant has already redirected its resources even without removal of the undergrowth.

Thank you for your post CannaRed You mentioned the best cannibiculturists (copyright me) and trust re. a specific subject matter (defoliation).

In general, I believe some of these resources have helped perpetuate many myths. I guess the lesson to us all is, don’t blindly believe everything you read.

This thread is specifically about whether something is a myth or a fact. I'm fine with admitting that I don't know the answer but it would be cool if those that profess to know the answer could back it up somehow.

I support the validity of your argument. Now it is your job to carry out your own research while seeking corroboration wrt your beliefs and compare/corroborate the validity of the research you conducted, instead of coming here and seeking to be spoon fed, which is how society behaves these days and, I am sure that if you bring up points of discussion/questions. I am sure folks will engage in clarifying your questions for you, with open arms. Instead of coming here like a bull in a China shop, making all kind of rules with regard towards the thread direction which isn't even yours to start with!!! Be well

IOW It's what works for you, in your own unique environment and conditions. One myth we can debunk right now is watering to 10% run off. It might be fine for coco but doesn't apply to soil based mediums. That was right from my local hydro shop who set me up in HP Promix as the easiest medium to deal with as a neophyte (like the TV commercial, "set it and forget it"). I never looked back. When I flush my plants at the end, my pots remain wet for 5-7 days. Roots need oxygen! When I look at some of the threads on here wrt plant deficiencies, a lot are in coco or hydro (some for hydro), yes they also include soil based mediums, but IMHO soil based mediums aren't as problematic as the other two, until you get some mileage under your belt, stick to what works for you.

I will second Switchers statement. Sucker branches are nothing new.

As in leaf, its sugar, but its also can "get int the way".

Outdoors vs indoors is also something to consider., much because of the lightning. I didnt take any leaves for years indoors since I thought it was stupid since I started outdoors. I tried it, not I do defoliate in some situtation some, not sure on weight but % of quality buds goes up IF the leaves would impair the buds development.

Outdoors I would take so much leaves, maybe some in case of mold an such, but I would still care about sucker branches...

Absolutely There is no comparison between indoor and outdoors. Outdoors mother nature knows what is best. Indoors you control the environment which in large part is artificially reproduced and personally I don't give a rats petueh... nobody on here is as good as or can replace mother nature. Large fan leaves which are necessary during the vegetative phase, become less efficient as time goes (right from Cannared's article). Yes they feed off themselves for water and nutrients and do not necessarily tap into the main reservoir (roots) to cool and feed themselves. However, when both nutrtion and water has been depleted, they will get it from the soil/roots. As there efficiency decreases over time, it is MHO while there are doing that, they are also rationing H2O and nutrients to the most vibrant/demanding part of the plant.

Where have I done that? I've asked for evidence that's all... thinking that it might help other people who were reading the thread. Isn't that the point of myth busting?

Why are you directing this at me and not the OP?

 

[Marz]

I always understood it to mean information gained from experiment - such as growing clones side by side and keeping all factors as equal as possible except one (cutting off lower branches for example) - and then telling people about your findings and then lots of other people doing the same experiment to see if they get the same results as you.

[Marz]

I always understood...

Sorry for the message above guys, jumping kitties matter. Not allowed to delete it.

Thanks for your insight.I said a fact due to a comparison between my growrooms and other ones I've seen around along the years, specially in forums like this.
The real experience is made side by side, I agree. After all these years I'm growing my first plant with a "main cola". Letting the plant grow naturally is certainly part of the experience and emulating as much as possible the natural conditions with a good, truly organic soil, naturally balanced with time and soil agents, will make the experience even more satisfying.
In the end I'm not here because of yielding. I wanna remember how to enjoy the ride properly.

 

[JKD]

Marz is correct in that empiricism is knowledge by observation or experience. El Timbo is correct in that to be accepted as valid research the experiment must well designed and repeatable.

 

[Switcher56]

Agree! Optimum would indeed be a side by side. I don't have that luxury, and clones do not fair out as well (which I don't do). That is a known fact that seeded plants perform better under these growing conditions.

As stated in post 8 I will repeat my latest run/experiment to verify/validate my conclusions in order to provide empirical data. To satisfy myself and prove my conclusion or tweak in the future to encompass lessons learned. I don't grow for an audience. This will be in a couple of years folks so don't hold your breath. My next run scheduled for the 24th Aug will comprise of 2x Ringo's Gift, 1x Harle Tsu and 1x King Louis, which will be a full 8 top manifold with mainlining. I know they will be 3 different strains etc... My runs were getting progressively better, until the last one where I never mainlined. I know what I am capable of achieving in my environment. The run will be a litmus test so to speak, during the interim.

Mein nächster Lauf, der für den 24. August geplant ist, wird aus 2x Ringo's Gift, 1x Harle Tsu und 1x King Louis bestehen​

and what great insights do you think you can gain from such a small number of plants per variety?

sorry but it is very naive to assume that you will gain even one lasting experience from it. which you can then generalize about a particular species is nonsense.

take a look, we used to plant 600 plants of the same variety. 3x200 each with different pH values. 5.4 - 5.8 - 6.2 everything on coco.

to provide empirical data

without mass they are completely worthless ... but have fun with your groww

Agreed…Peer reviewed, statistically significant research done well with a large sample population is the best way forward to improve our understanding of cannabis.

That doesn’t mean anecdotal evidence is not useful. It’s where many of the hypothesis that lead to research come from, and it’s useful in finding problems. Or maybe it’s just a newbie’s laziness. Hell, I don’t know.

Peace…Jeff

In practice, I use low stress training and supercropping to keep maximum foliage in the optimal light zone.

"The influence of abscisic acid (ABA) on plastidial and cytosolic terpenoids and on two key enzymes for terpenoid biosynthesis was determined in vegetative stage of Cannabis sativa L.

Low concentration of ABA (1 μM) increased 1-deoxy-D-xylulose 5-phosphate synthase (DXS) activity in treated plants in comparison to control plants. The amounts of chlorophyll a and carotenoids increased in response to ABA treatment but chlorophyll b content declined.

The accumulation of α-tocopherol was stimulated only by 10 μM ABA. The ABA-treated plants showed a decline in 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) activity which was followed by a decrease in squalene and phytosterol content.

ABA also decreased tetrahydrocannabinol (THC) and cannabidiol (CBD) contents. The essential oil had higher ratios of monoterpenes to sesquiterpenes as ABA-treated plants had less numbers of sesquiterpenes in comparison with control plants. Influence of ABA on the amounts of sesquiterpenes was different, some of them showed decrease of content and others increase of content."
