Conclusion:
The contents of metals in rhizosphere soil could be an indication of the cannabinoid content.
This work could *** a contribution in an attempt to determine the geographical origin of
Cannabis sativa plants according to the correlations of metals and organic compounds responsible for cannabinoid production.

Finding me..??? by checking the plants for my soils ID????
no chance ...but still a good find
thanks Doc.

I Fe el ya.Fuck!
Anyone know how to get Irridium out of soil...?

My understanding is that Fe and Mn should be close. Ive had nice results with both at 100ppm. Pro's tell me that it's wise to bump up Mn just a little bit at a time like 10-20 ppm. I think approaches to leaching iron depend on pH. I dropped Fe ppm's in my 6.5 recycled peat based soil with gypsum.
The topic in the paper I attached discusses data similar to OP. In this example Mg and K are shown to antagonize potency while Mn and B support THC generation.
Re: Mn. AEA's product Accelerate packs a wallop of Mn without much NPK but with other seaweed and mineral inputs. I've used both Magnesium sulfate and Accelerate with good results. IMO dont even think about this type of action with out a soil test.

Woh.... hold up... Those are toxic levels of both Fe and Mn... 5ppm of Fe is on the high end and 0.5ppm of Mn is plenty. (those are actually the levels i use in mix #21) 2ppm of Mn is the highest I've seen in any recipe. 6.8ppm is the highest I've seen for Fe.
You can't be serious...

Lol No my friend, you're the joker ~10 ppm Fe toxic??? uh uh come again
Maybe we are using different scales. I'll post up my soil report from spectrum analytic. Pretty sure the ppms are 104 Fe 94 Mn. The pH is 6.3ish. It produces huge flowers, zero pest pressure, no mold issues, sweet smooth flavor and fragrance.(using the 13.5/10.5 schedule I learned from you)
These values are from a recycled, peat based mix that I test at least 1x per year. I have some old reports to compare.

Samples are from same mix about 16 months apart.

Well good luck with that... I thought you were talking about the reservoir solution in hydro, not the medium (soil).

The Cornell paper said: "Band application or foliar application of Mn fertilizer can eliminate Mn deficiency while broadcast application of Mn to soil is not cost effective and therefore not recommended"
The Amazon ad you linked to said "Most Efficient When Applied as a Foliar Application".
Band Application from: https://courses.cit.cornell.edu/css412/mod5/ext_m5_pg4.htm
Fertilizer can be placed in a "band" often 2 inches over and 2 inches down from the seed during corn planting or drilling small grains or forage seedings. Since it's done in the same motion as planting, it's also called a "starter" application (i.e. to help "start" the plant off). The band is close enough to efficiently supply the young plants with nutrients, while not so close as to damage the developing roots through salt burns. Check out the diagram, below.

The article I posted is an really an advertisement for some mineral foliar spray. Not sure why everybody is liking the paper.
I put it up to show that there has been 1 test published on this and a "doctor" already sells a product based on it.
The idea that it one or another element is key or adding something extra will make more thc is ludicrous. Balance is key for life to thrive.
Maybe I should produce MMG's super fantastic marijuana booster spray. Pure "ionic" water in a special mister that lubricates and adds vigor and helps nutrients mobilize and become effective.
Water. Spray it on your plants and see them flourish. Proven by professional Horticulturists.
Lol.

I doubt anyone is reading the paper or liking it. Any response, at least on my part, is about the OP not the paper.
I quoted you becasue you mentioned foliar .
I see no issue with foliar application. In 1976 I had five plants which were fertilized once a week with a foliar application of Miracle Grow. It worked very well.
My reply was in response to possibly using the wrong application method.

Got ya.
I never foliar feed indoors to avoid the mess but I do understand it works very well. A micro nute foliar could be very beneficial.
It's the article that mentions foliar I was repeating. It leads to an ad for ionic spray micro nutrients.
And it was only 4 people liking the article posted. Just felt like more. Lol.
I learned dyna Grow is testing for a cannabis fertilizer now. That will be interesting to see I think. They will know the right elements and ratios.
The rest of this seems like profiteering to me. Plants adapt. And they only need what they need. They even can transfer photosynthesis to any light spectrum available. They can even substitute salt for potassium if neccesary. So trying to flood them with a "Magic" element to get better results is not effective. And will likely cause other nutrient antagonism. They prefer balance and variety in small doses in my experience.

That would be most true for outdoor applications.
Yet Arborists do exactly that for longer term availability to tree's. The problem with many trees needing it is the tree being in the wrong area for Mn. Many area's around the country lack the proper Mn concentrations for some trees needs. Palms require a surprisingly high amount of Mn. If that amount was available in the soil that we grow in. It would be a toxic amount to most plants we grow, including MJ. The only way to apply Mn for use by palms is soil by supplementation! If you cross reference that by Arborist notices by major universities. The way for all tree supplementation is also by soil application.
I give my point - regarding container soils! After all, your adding such a minor amound! At build time - add the Mn by putting it in your wetting. I do my FUL-HUMIX at the wetting, so why not add that 1/2 tsp per cft to that. Thing is with a foliar application. Your going to have to use a very, very small amount of Mn and risk of a tox problem is down right probable.....The product MMG refers to is desalinated, and concentrated ocean water.......Sounds rather snake oily to me.....
Bottom line is that soil amending is the way I would try......Not like it's expensive to give it a shot anyway.....
There are people who try anything to increase potency. I supplied this one, because there is actual science behind it.
Try it or not but, I feel you did not research the application of Mn for plant use by supplementation enough.
Opinion is opinion though. So your post is noted.
My reply is on my chosen application method and why......

REALLY?
After being given a paper on the subject and backed up by another members posting of another paper that not only backs up the subject but that he has had success with? He even includes what he's used and had that success with.
What a single compound can do for plants should be noted by what leaving a single compound out would do.....
This post =
I saw that about the relationship between the Mn and the FE in arborist publications on amending outdoor soils for tree's with def's.
I should have posted something about that.
Yet the info you give is golden in that respect......Again, nice posting on that!

No man. You took my quote out of context. I was referring to the paper I posted. The ad article for the snake oil. Not your link and the other one from Cornell.

Your are correct. I did zero research and know nothing about how to apply Mn. I only looked at the content you posted, and wrote what was in the content regarding application. Then did a search for "band application" and posted the diagram from another Cornell document.
The key word was "possibly" when I said the method was "possibly incorrect" . I used "possibly" explicitly because I did not want to say you were wrong. The Cornell document in your post did not include blending or mixing.
I considered getting some of the Mn sulfate on Amazon as a food additive because I think my diet needs more Mn.

Cool. Eat more trout and spinach, those have the highest natural Mn content. Fish or leafy greens is the basic answer.
