I wrote this (mainly) in another forum and for all the dribble, opinionated crap and boring threads i write i found this to be absolutley A+ 5star material.

Its a touchy subject here but i really think it stands out from all the other drool i contribute, possibly my first and only decent thing ive ever wrote on the subject of mahijuhana-


"Just thought id do a small thread on this subject, although confusion for most i think this describes the process for most plants and why we see purple in our plants.



Anthocyanin is the glucoside of anthocyanidin -

https://en.wikipedia.org/wiki/Anthocyanidin


When anthocyanidin combines with sugar it forms the purple pigment anthocyanin. Anthocyanin is increased in plants that are fed high sugar diets.

Leaves of plants can be considered the 'source' of sugar production and roots could be considered the 'sink' as they consume the sugar. A sink can also become a source as its resources/stores are called upon.

The primary job of anthocyanin is to bond with these sugars in a reversible reaction so the sink is not overloaded by the source.

We see seedlings develop purple leaf undersides and stems as the leaves (source) produce more sugar than is needed by the roots. Photosynthesis is often limited by Co2 and not the need for sugar by the roots hence overload can occur.

Anthocyanin is not thought to scavange free radicles and oxygen species.

Increase light will increase photosynthesis past the need of the roots and the link between photoinhibition and root sugar levels.

A general sink to source relationship problem can occur with cold roots as they will not grow as fast as the rest of the plants leaving an excess of sugar that is not used by the root.

We see purple stems from a variety of reasons but im quite sure it corresponds to the sink/source relationship of sugar production within the plant.

When peeps talk about purple in genetics it is more often that a mutant with a weaker sink to source transportation system was selected for breeding and hence the tendency to show more purple colours from this sugar relationship.



Phosphorus deficiency -

So to complete the cycle it is vital to understand the relationship between phosphorus and anthocyanins or purple stems and leaves as it also induces sugar problems within the plant.

The production of sugars during photosynthesis and the conversion of these sugars into energy during respiration enable the plant to perform all other life-functions. When respiration is restricted due to a P shortage, sugars are not converted into energy and they accumulate within the plant tissue. The accumulation of unused sugars leads to the purple coloration often seen with P deficiency. The low energy level within the plants is the underlying cause of the stunted growth typically seen with P deficiency. When energy is low, all plant processes suffer. Flowering and reproduction place a high demand for energy on plants (not to mention the need for DNA in seed production after fertilization). Therefore, adequate P is essential to the process. A plants ability to generate abundant energy becomes more important when it is put under additional stress, such as cold soil and air temperatures."


So we see purple from a P deficiency because sugar cannot be converted to energy and thus builds up in plant material.

lot of incorrect scientific BULL SHIT above . most of it incorrect . sugar is carbs for any plant . put some in the water they will drink it . and if they require it the can make use of it . freaking getting all scientific .

take all of the fun out of it . every farmer even lawn boys will have to go to collage for 10 years ! wow. how much would it cost to hire some body to cut your grass if every body thought like the poster above all technical . it would be a 5day session and safety checks just to pore the gas in and many permits and licenses hefty insurance .

I gave you all a like.Yes you are correct it is quite scientific and i do apologise but merely wanted to judge wether this or a more advanced forum was the right place to hack apart those purple stems and give meaning and reason to the whole process whilst including all criteria such as temps, ph, nutes and deficiency.

I will keep the more technical stuff for the more academic forums but thank you all for taking the time :-)

Outside of reading journals on agriculture that cover that topic, there's no way for me or anyone here to properly verify the information without spending money and just fucking around with plants. One a topic like this, it's not feasible. On a topic like your basic fertilizers, it's absolutely possible because it's a simpler subject to understand.

For a home grower, it really just doesn't matter if it's correct or not.

Also, what are these more academic forums you are talking about?

I disagree, the source to sink relationship is visable in most grows but with no application you dont know what your looking at. Ever wondered why unshaded leaves close to the light have purple stems and those shaded leaves underneath have green stems? perfect example of source to sink relationship.

So many threads on purple stems yet you ask me not to address the subject!

Those academic forums are where the academics hang out and youll find them if you want to.

Your posting of this and then asking what we think about the content just got me thinking a lot. Mostly in regards to what a basic home grower is going to understand compared to a professional and how everyone tries to work through that to sell shit or market shit. And I use shit specifically as a term to describe products that are marketed with psuedo-scientific bullshit vs actual scientific results behind them.

No i posted it elsewhere and got a good response, my only reason to post here was not to sell you shit but to see if i should carry on here or stay elsewhere.

I said above that i would keep the technical stuff to other forums, apologised and gave everyone a like for their contribution, was the least i could do for bothering them now troll of and quit bothering someone who actually does ask questions and fucks about with plants for the answers!

I don't want you to think I was trolling you. I certainly was not. I know you aren't trying to sell something. And I think the content itself is useful, I just haven't read enough on the topic to verify it. I was was just thinking out loud, I guess.

I dont know any that troll its just a saying i like.

Purple stems is from a lot of reasons you just need to find the one thats not right to green the plant up.

Simply put - Anything that affects sugar in a plant can cause purple. For a more detailed explanation see my first post.

I was going to write a lot more on the subject but i didnt know where was best so this was like a teaser.

We also have an Advanced Marijuana Forum here and sorry for being a douche as im in middle of giving up smoking so a little more tense than usual.

Peace dude :-)

Well, I for one would love to read more of what you have to say on the subject.

Purple stems is the six million dollar question round these parts, ive long pondered and looked into it.

Click the link in my sig below and thats as far as i have got, should take you to my thread in advanced mj cultivation forum.

This is still quite a new discovery to me and vast amounts of research was gleaned from the Cornell University and Wiley online academic research papers.

If you need to ask anything do it here as the other thread is still a work in progress.

I am suprised this isnt more prevelant in the comunity but a lot have the right idea as temps, phosphorus, light etc all cause purpling and many members already know that but no one thread seems to bring it together.

None of this is aimed at growing i just put it out there as a consideration and contribution to this great site. Most of us know the basics so getting technical seems a logical progression.

Peace and enjoy some knowledge :-)

Intersting isnt it, google 'Sink to Source in plants' for more on the subject and enjoy.

Did i mention KISS Keep It Simple Stupid' - our motto here. Its great to get all scientific but its still only about providing your plant with the basics and a good environmemt i.e. dont overcomplicate things just cause you read somthing.

Yeah, growing plants is easy. I know. :)

Growing cannabis is exactly the same as growing any other cut flower plant, much like poinsettias, for example.
