Iām mostly looking into what things brix can tell us that ec measurements, runoff pH and whatnot canāt. Seems like less defol and harder dry backs both seem to drive sugar into tissue.

Iām quite new to scientific research but I do scientific research on cannabis plants. I mean quantitative scientific research that considers experimental design and statistical analysis. Also, am familiar with plant ecophysiology. Hopefully, my comments can clear a few things.
So few facts about plant physiology or ecophysiology.
Unnecessarily high brix most likely means your plant assimilates balance is off or has a higher chance to be off soon.
That means your plants are susceptible to pests and diseases for instance. Of course, there can be an ideal range where youāll get more sugar production without problems but it doesnāt mean your plants are healthy. It means your plants are strong. Just that the healthiest plants are balanced plants, not necessarily stronger plants.
Indeed, healthy plants often indicate better bud (flower development) but a healthy plant doesnāt mean your cannabinoid and terpene production will be higher. Itās more likely the other way around since especially, cannabinoids function as a part of defensive mechanisms so a stress response.
Sugar production in plants has nothing to do with microbes.
Well, yes, plant interacts with microbes and often plant sap that has glucose in it, is involved in this interaction. However, it has nothing to do with plants making sugar. Also, less meaningful amounts of sugars are used to interact with microbes.
Another thing, I want to emphasize is that the majority of nutrients are fed to plants via plant water uptake, above 85% of all the nutrient uptake that plants do during the life cycle.
Please donāt think plants select what nutrients to uptake every time. That scenario is an extremely minor case.
Back to sugar again, if you want to know if your plants are having excessive sugars, look for the stem/petiole colours. If purpling, that will indicate a trend that your plants are getting excessive sugar probably either because of starch accumulation or anthocyanin accumulation. Both starch accumulation and anthocyanin accumulation often mean excessive photosynthesis compared to respiration. This way you can assume that your plants have relatively higher sugar than under ordinary conditions.

My exact thought when I saw the post.

Curious what unnecessarily high brix would be.
Any sources on this? I tend to disagree pretty heavily.
Chemistry decides what uptake ratios are in plants. Itās not really a plants choice.
Iām a little confused on what your point is?

What about nutrient issues? Lighting responses? It really isnāt as simple as 1 leads to 2.

Any accumulation that exceeds the function of the buffer is unnecessarily high brix. Simply called that the assimilated balance is off.
If it is conventionally considered sugar in plants is produced by photosynthesis, I think it should be you who brings scientific research source that proves microbes directly create/transfer sugar for plants.
Perhaps, this can help indirectly with sugar.
Personally, never looked into scientific papers about proving sugar production mechanisms in plants. Simply because those researches are already fully done and now itās sort of law (not really) that people in plant science/horticulture learn this during the first chapter of the basic plant physiology book, rather than the people get to learn this from a research paper.
- I meant that microbes do not do anything about sugar production in plants.
In fact, microbes use this sugar not produce it. For instance, the sugar in plants, which is produced by photosynthesis, is used to feed microbes.

Long way to say we agree. If you have anything meaningful to report on brix, Iām here for it. I havenāt seen you post any resources or really claim anything that we donāt know
What do you mean lightening responses?
I can think of two light resposnce.
- anthocyanin trying to absorb 550nm of light spectrum to decrease photosynthesis activity.
- Starch accumulation is also a response to light, which is byproduct of leftover sugar that can be used up by plant respiration since itās too excessive or respiration rate is too low.
Nurient deficiency can def play role, such as phosporus in this concern. But cannabis is such a short cycle crop, for professionals, it really is hard to expect to have nutrient deficiency in cannabis plant. Nutrient deficiency is more worried in crops like highwire tomato/cucumber/paprika/eggplants where you have to take a plant year round. Cannabis only goes 2-3 months. Outdoor can be different but personally, canāt say much about outdoor. Donāt have experience.
But yeah, letās say there is someone, whoās nutrient is chaotic, radiation to temperature ratio is chaotic, irrigation is chaotic and so on and on, canāt directly give a 1 to 1 clear answer. I mean no one in the world can direcl in that case, itās more of gambling from that point.

Iām sorry. What? Cannabis is one of the only plants known to not have a light saturation limitā¦meaning itās nutrient use is dependent on lighting and CO2. Itās far more intensive on nutrients than tomatoes or cucumber.
And again: resources are awesome

Whatās your point is a better question?
Microbes are part of what makes sugar useful to plants

you are joking buddy.
far more intensive on nutrients than tomatoes or cucumber 
Literally high wire crop goes meters and meters. They are tall as much as tree and you are expecting 1 meter indoor cannabis plants to me more nutrient intensive.
and definitely, I wouldnāt waste time educating you or finding sources. I just suggested direction cuz some people are talking nonsense bro science sht. But due diligence is on you, not me.
I guess your saturation stuff is coming from bruce bugbee. LMAO cannabis plants also have a saturation curve just saturate slower.
