xD maybe publish your well documented experiments into a book and make it validated scientifically... for now it seems only broscience.
Weak stem, what can i do?

a very strong argument ... and so grown up
Ok thanks for the suggestion f-e! My tent spec is 60cmx60cmx158cm and right now the light is 60cm above the highest top of the plant. I tested some training now to make the plant grow more like a bush instead of a tree (pic below) and you also see my little baby hehe. But are you saying that i should lower the light 10cm or?
maybe not coincidence there are no books released on your thesis.
argument over.( well there were no arguments)

i don't see a fight .. what i see is a person who has no arguments ... but gets cheeky.
maybe instead of try to troll my advice you should talk about other facts, for example the light mix, and the insufficient nutrients to support the development of the plant. but your biggest problem is my advice ? sorry to hurt your feelings with the wind ... and yees i still disagree with your thesis, that wind has no effect on annual plants.
Wind stops a plant from stretching. Brushing their tops daily is a stretch reduction technique that takes advantage of this. Leading to a more uniform growth. We may see this automated in greenhouses one day.
I can only guess that a plant feeling too at risk to elongate, may instead get tougher. I mean... what else is it going to do? Certainly the idea of fans strengthening plants is an old one. I have not seen this myself though. I see P as building strong plants.

you misunderstood me ... you get this advice anytime and anywhere ... but it doesn't change the fact that it is a myth.
I'm not saying that it hurts.
it just interested me more intensely ... and you can find the answers in the architecture of the plant ...
if you took it like I was attacking you ... no, I didn't.
But I have never met anyone who could reasonably explain why a plant whose trunk does not depend on being rigid but can swing in the wind because of its flexible phases ... should get a thicker trunk due to the wind.
I didn't mean anything bad to you ... but the argument because it is in a book you can hear it everywhere ... a reasonable reason for why ... you won't get it then.
Indoor on the thickness of the trunk ... don't turn the words in your mouth.
outdoors, strong winds have a huge impact ... these plants tend to be low and bushy ...
stay fair in the discussion!
plants act same indoors as outdoors, only difference is you have to make the circumstances artifically... and no mothernature to help you with it

a very superficial view ... indoors you will hardly be able to immerse yourself in the world of stimuli and impulses which mother nature offers ...
Indoor you do not make thicker trunks with a fan that is set strongly than with light air circulation.

than you should just add CO2 in an airtight room. and don t need any air movement/circulation. "light air circulation" is not air movement at all.
wind is only wind over 100km/h?

Many studies have shown that wind affects plant development, causing them to develop shorter and usually stronger stems. Many of these effects have been shown to be due to a response to mechanical flexing of the stem which is known as thigmomorphogenesis
Google for the term thigmomorphogenesis if you want more information.

I know these terms and reports.
However, it does not change the fact that it is not essential for cannabis to have an upright trunk.
you can put the stem in the scales during the growth phase ... that's not a big problem for cannabis ... thanks to its flexibility it aligns itself back towards the light.
with perennial plants it is something different ... they react to the experience of past years ... and adapt for the future.
but our plant has only one goal ... to hibernate as seeds at the end of the season ... it doesn't matter to you whether this happens lying on the ground or standing ... as long as it does not suffer any significant loss of light.

Comfortably numb!
Stake it at a couple of points. That is/was the result of growing in a window. Wrt fans you mention later, do not point your fan on your plant. Positioned strategically in your tent (bouncing air flow against the walls), will provide enough turbulent air flow to provide said movement, without damaging the plant.

Thank you all for the advices and the ongoing support, you all are really just amazing!
As i said and showed earlier i tied my plant down yesterday and its already showing good result and i see alot of new growth all over the stem that is facing up towards the light so i am happy and will continue on like this and show you all in a week or two the progress.

f-e i did a little more detective work regarding the strain and i think you could be right in thinking it is Super Lemon Haze. I dont know if it is characteristics for just this strain but the branches on my girl is a slight purple and its the same on this pic of that strain https://shop.greenhouseseeds.nl/feminised-cannabis-seeds/super-lemon-haze/
Looks like a really good strain so heres to hoping
Do what other posters have suggested, as far as staking it up and using a fan. Air resistance will stimulate it to grow a stronger stem. Make sure it's the proper distance from the light, probably closer then you think is necessary. Strong lighting and loose, airy dirt are necessary for healthy stalks and roots. A leggy plant with poor stem and root development is susceptible to dampening off, fungus attacking the roots and stem base. You want a well-draining soil with proper nutrients. You want to be sure not to overwater. As long as you provide good conditions and stake it properly, forget about it. I mean, don't worry if it looks leggy or doesn't seem to be developing the way you think it should. You've done right for it and it'll respond and grow well.
