Start to finish how much nitrogen does a marijuana plant need.

The post about corn is closest you will get to lbs per acre, thats how row crops are prescribed amount of fert per acre.

Too many high-pot-heticals to figure that one out, just keep it simple!

I found this for corn it is what I was looking for in cannabis.

Corn is a well researched crop by the big AG universities. My guess is they are discussing the most common forms of commercially grown corn too. High THC Cannabis can not be researched in the US. Israel has done some research but there is so much we just don't and won't know until it can be researched. So you can extrapolate based on what you plan to feed or add up your journal based on what you did feed but that's merely anecdotal to that crop. Best of luck in this, I'd love a lot of these answers too.

PS I would guess that heirloom corn varieties would vary from that amount.

I thought it was heavily researched by Bro Science

That's really some of the problem, all we have is correlation so pseudo science is perpetuated and stoners like to ponder things, so here we are. The path forward is via questions often asked by high as a kite graduate students.

Grow out a plant in hydro. Measure the exact amount of nutrients you used. Do some fun stoichiometric calculations to figure out exactly how much of each you used. Yay, public school !

More or less.

How long is a piece of string? How much does a house cost? What is reality?

Life is simply full of unanswerable questions.

Pothead insight forthcoming:
While it's useful information to give a recommended N concentration, the question was the total weight of nutes used for an "average" 6 foot plant.
Sure, he could feed at 160ppm N but that doesn't answer the unanswerable question of total nutes used for the hypothetical plant.
PPM is only one part of the equation; frequency and duration are unknown.

Yes you are right, I have the info ( frequency and duration ) from that study but it's not for soil.

Nice, thanks.
