Sorry, misread, edited out my erroneous comment

This is actually really poorly written and for the most of it they are barking up the wrong tree


Yes, I agree that it's not the best, but it's not as far off as you say.
 

"If we know that we cannot expect P to be found in higher concentrations in the roots and blooms than we find in foliage, how can we justify the belief that massive doses of P are important to their formation?"
 
Storage does not imply use. If this statement were true of humans then a regular diet would be 80% protein, 15% fat and 5% carbohydrate whereas it's closer to 20/40/40


If you were using humans as a hypothesis model, sure it would be. But that's a strawman. Comparing large and long chain molecules to individual nutrients? Come on...

Nutrient storage is absolutely used as a criteria. It's often referred to in conjunction with terms like "accumulation", "storage capacity", etc. In fact, plants are metabolically compartmentalized, based on roots, foliage, crown, etc, and testing can be conducted to see how quickly nutrients are used locally within each of these areas.

"Simply limiting N limits vegetative growth, but it does nothing to limit photosynthesis. The plant keeps making food, but it cannot use it to grow leaves and extend stems because of the lack of N. To where should we imagine the energy goes? It goes into producing blooms and fruit."
 
I don't even know where to start on this one, it's just an imaginary process. Excess sugars from photosynthesis are stored as starch in the vacuoles until needed.


Except that you are ignoring the fact that certain macro and micro nutrients become the vehicles for metabolization of said stored energy. N, being one of them.
 

"We know that tissue analysis of leaves, roots, flowers - any of the live tissues of healthy plants will reveal that P is present in tissues at an average of 1/6 that of nitrogen (N) and about 1/4 that of potassium (K)."
 
So why would limiting N cause it to flower when every part of the plant has equal ratios of nutrients? The hypothesis of limiting N preventing vegetative growth in turn causing flowering does not make sense. Studies done on the UPTAKE (not storage) of nutrients show that nitrogen intake actually increases during the flowering and fruiting stage

You can't increase uptake of a nutrient that isn't present. That's the whole point of LIMITING. As in, not making it available, to begin with.

The point was that the plant, being an efficient organism, alters its nutrient cycling, based on availability.
 

"P competes with iron (Fe) and manganese (Mn) ions for attachment sites and causes antagonistic deficiencies of these micronutrients"
 
No it doesn't. Iron, Zinc and Manganese deficiencies lower the amount of phosphorus required for toxicity.


The context of the article was an overabundance of P. In a healthy plant, with proper nutrient ratios, it's not being suggested that there is an antagonistic relationship. Only when P is too high. And we know that P lockout is a real thing, so it's one attempt to explain the mechanism. I honestly don't know if that part is true or not.

Here you go. This isn't a guy that I'm overly fond of, but when someone is right, they are right. Start reading what he's posted, and then start trying to debunk it. That's when you'll start to really learn something.

The tricks we think we play with plants, sometimes, aren't really anything but smoke and mirrors.
.
Just wanted to draw attention to one thing of special note: (that I touched on earlier, but just noticed)
.

Evidence of phosphate overfertilizing usually always includes some degree of leaf chlorosis. P competes with iron (Fe) and manganese (Mn) ions for attachment sites and causes antagonistic deficiencies of these micronutrients. Unfortunately, the deficiency of these elements causes interveinal chlorosis (yellowing), and the first thing we normally consider as a fix for yellow leaves is more fertilizer, so we give the plants a good dose of our favorite bloom-bomb which causes, no surprise - worsening of the condition.

I'm trying to be in the big boys league (producer quality) in my garden.


If you want to be in the "big boys league", then you need to plant more plants, not try to squeeze more production out of a fewer number of plants, by megadosing. Just saying, you are barking up the wrong tree. I don't know how new you are to growing, but the best thing that you can do, is to really understand the science of what makes plants grow. It's simpler than we make it, most of the time.
.

We have very short growing season (< 3 months without a freezing night)

 
Organics (emulsion,compost,wormcastings,etc) and pellets are slow release fertilizers.

.
First off, building a soil, is to incorporate slow release elements. You rely on building a microbial colony, to digest said amendments. However, you are still a few months away from the actual growing season. It's more than enough time to get organics started. I'm not trying to get you to go that route, just pointing out that there is plenty of time, if you like the option to use organics.

Secondly, fish emulsion is most certainly not a slow release product. Any kind of organic that has been emulsified or hydrolized, is, in part, immediately available. Because the particles have been broken down to their smallest feasible size, they go straight to work. I use fish fertilizers here, even when the temps drop below the 56 degree threshold for microbial activity - and yet, the plants grow.

I read commercial blogs mostly and some hotpepper posts. 420 like forums are the worst mess around regarding facts backed opinions.

.
If you read marijuana forums for pepper advice, then God help you. Those people are the main reason that most of the bullshit related to growing is propagated. They are the reason for so many ridiculous unnecessary fertilizers and amendments. There are some really sharp weed farmers out there, but they're in the minority. Most of them get suckered into the nutrient hype by the picture on the bottle.
