No bro, it might be a scientific paper but it looks like you are misinterpreting.

You believe this paper is a basis for feeding low N? Use your scientific rigor to explain how the thc content of dried male and female leaves is useful for determining the content of thc in female flowers.

"Cannabinoid content of the leaves is known to decrease gradually from the top to the bottom of the plant (Hemphill et al. 1980). Nitrogen content in vegetative parts of the plant has been thought to correlate positively with its THC content (Coffman and Gentner 1975, Haney and Kutscheid 1973)."

The paper actually is crystal clear. It never mentioning the fruiting parts.

Can i have links to those two papers, i cant reference them on google, please?

What ever dude, plant matter is plant matter. Hemp growers grow for fiber and if the THC goes over a set amount it can't considered hemp

How bout you try it for yourself and see if I'm misinterpreting it ???

"what ever dude" lol i thought some science was coming my way.

Your claim and your citation are bogus. Using hemp growers as an excuse is irrelevant. Youre not growing hemp.

I dont need to try it for myself to determine that you misinterpreted the paper. The paper is not a valid basis for your assertion and it nowhere states N lowers THC in MMJ.

by "more wrong" you mean that i have shown your conclusion is not supported by the citation you provided?

You haven't done any arguing you are slinking away from being exposed as a phony.

"immature" is not what it is called when someone demonstrates that you are talking out your ass.

"act adult" lol, you mean you're going elsewhere to assuage your case of the vapours?
Thats good news. Defending the leprechaun is not a role for the faint of heart.

If sulfur feeds trichs, that must mean trichs are high in sulfur, right? Which chemical is the sulfur tied up in? Which terp and/or cannabinoid contains S?

I'm pretty sure none of them do.

Sulfur feeds the chloroplasts. Sulfur and iron are both needed to produce the ferredoxin proteins required for electron transfer in PS1.

You have no choice with mj ferts, all veg ferts are highest in Potassium anyway.

With all do respect to a fellow member of your caliber.

You have all the choice in the world.
Use what you like.
You can mix your own if you like! Mr. Blah does! (Where do you think all that ratio math is from)

Just to note. If you would take the time to add up your end NPK ratio's for most "MJ" fert's (really, there's no such thing as "MJ" fert's) .... You would find them higher in P with an ok K level.....I always found myself supplementing the K to where I wanted it!


I build my soils - high K and do 2 stage soils...One for veg and one higher again in K, for bloom!

Did you guys know that some chemicals have more salt such as Nitrates? Did you realize that nutrient mobility has an index from 1 to 10? In LPA I don't have to worry too much about this stuff, I instead just run a low ppm with frequent res changes. But now that I have decided to learn soil I am finding it very important to fully understand this stuff. Not to mention how much better my LPA grow will perform if I get a better understanding.

Sorry to interrupt the argument please feel free to ignore me as I am fully ignoring the argument, ROFL

Yes and Yes.

Just about every fertilizer has two components. A cation and an anion. So, for example, calcium nitrate. Calcium is the cation, nitrate the anion. There are others such as monopotassium phosphate or magnesium sulfate or ammonium sulfate plus many many more.

Foliage pro is higher nitrogen and lower calcium, an obvious step away from your general mj formula, i like the nitrate/ammonia levels for soil in it as well.

Alright, so, in reading a lot of your posts, you seem to misunderstand ratios with chemical concentration.

Bear with me for a second, because this will all make sense in a bit.

First off, all fertilizers in the US are sold on a weight/weight% basis. This means a fertilizer that has a 2-1-2 on the bottle is 2% total nitrogen, 1% phosphate as P2O5, and 2% potassium as K2O, by weight.

Concentrations of elements in an aqueous solution, water, are measured in weight/volume. The concentrations that read as PPM, parts per million, are equal to a measurement of mg/L. So, if I add 100 mg/L of a 2-1-2 fertilizer, I have now has a solution that is 2 ppm total nitrogen, 1 ppm phosphate as P2O5, and 2 ppm potassium as K2O.

Lets now consider your calmag blend. You say it has a 3:3:1 ratio of N:Ca:Mg. That's all well and good. But it doesn't tell us anything about the weight/weight% of the fertilizer. If it says it is 3% N, 3% Ca, and 1% Mg on the bottle, then it's useful information. In which case, adding 100mg/L, which is 100ppm, of this fertilizer will give you a solution that is 3 ppm N, 3 ppm Ca, and 1 ppm Mg.

Now, let us consider a common calcium nitrate fertilizer. It is 15.5% total N and 19% Ca. So, if I add 100 mg/L of this calcium nitrate fertilizer, I will have a feed solution that is 15.5 ppm total N and 19 ppm Ca. If I want 100 ppm of Ca, I need to add more of this fertilizer. Specifically, I need to add 526 mg/L of it. This will mean I have 81.5 ppm total N and 100 ppm Ca. Now, I want to add magnesium to this. I chose a magnesium nitrate fertilizer. It is 11% total N and 9.6% Mg. To reach my 3:1 ratio of Ca to Mg, I need 33 ppm Mg in solution. To get 33 ppm Mg, I need to add 344 ppm of this magnesium nitrate fertilizer. This means I will also be adding 37.8 ppm of N to the solution. Bringing the total N concentration to 118.3 ppm.

So, a blend of the following:
526 mg/L (2.0 g/gal) of calcium nitrate
344 mg/L (1.33g/gal) of magnesium nitrate

will create a solution with the following concentration:
118.3 ppm N
100 ppm Ca
33 ppm Mg

This is a solution with a 3.5:3:1 N:Ca:Mg ratio.

I hope this helps you along with what you're working on.

I'm so confused on this subject and the whole ppm part , I have only ever done one indoor grow and I'm having a nutrient Deficiency , I think it's a cal/mag problem , but also I don't think I'm mixing my nutrients right and I don't have a ppm meter. My first run in my opinion was poor and I only pulled 2 lbs off form 1800watts of light in using 6 lights 3 over a 4x8 table with 32 5gal pots the lights are the Cdl 315watt Argo
