Nice walk-through. Last 10 minutes has some leads for searching up papers and works that staff and students have done. If you read the titles on some of the wall posters.

He's also got a great new vid on maximizing yields for the home grower.

Would be a good reference for newcomers to watch before posting for help. Interesting potting media, too. Like the mention of silica.

vermiculite is cool, while was astonished he point it out that much.
vermiculite is
SiO2 35,00 – 41,00 % silica
TiO2 0,60 – 1,40 %
Al2O3 6,00 – 9,50 %
P2O5 0,20 – 2,00 %
Fe2O3 6,00 – 9,50 %
Cr2O3 0,01 – 0,15 %
MgO 21,50 – 25,50 %
F 0,20 – 0,80 %
CaO 2,00 – 6,00 %
CL 0,00 – 0,50 %
K2O 3,00 – 6,00 %
CO2 0,60 – 2,50 %

btw, what you guys guess.
is he giving the 120ppm nitrogen all way through? till then end of flower.

I was curious about this too, so no flush is what he seems to be saying?

was asking myself if he go lower with N in flower like most do.
in a previous video he mentioned he prefer constant nutrient feeds.

I think he was just giving a good general guide, for beginners. Truth is this plant will grow with a variety of NPK ratios.
If you want to get more performance out of your grows theres lots of info on rollitup for media specific Jacks blends for veg and bloom.
You doing coco/perlite with daily application?
As time goes by, find myself leaning more towards organic sip style growing. It reduces system complexity. And can remove points of failure. Looking at peoples octopots grows which is sort of an intermediate type system, and then the SIP grows got me there. So many ways to stroke this cat.

If you are doing experiments, you want to limit variables. Using a fixed nutrient ratio helps when conducting experiments where you want look for example, at effects of light/ light quality.

its not clear to me.
one could guess he give the same mix from start to finish, low EC.
i try to aim almost 120ppm N in veg, while i reduce in flower to not more then 80ppm.
am aware of the common jacks ppm, using atm perlite/vermiculite watered 4 times a day.

that can be, at least then he dont see a big problem in a elevated N level in flower, i am just guessing here.
higher N level have the benefit of a higher C level too if one use calcium nitrate.

this is from a fertilizer manufactorer, true for all plants, they say.
just throw that in, sorry if thats too far of the thread topic.
ah regarding SIP, yes there are tons of systems, atm i use simply hempys, they wick well and are easy, silent n cheap, basically also just a SIP.

Maximizing Cannabis Yields for Home Growers with Dr Bruce Bugbee
This is a basic guideline. Don't think you have to read into his nutrient recommendations as being the absolute gospel. The average newcomer, could gain a lot of saved time, sweat, and tears by just following that guide in the attached video.
But if you want to advance, and apply adequate and economic level of the correct nutrients you are going to have to approach from a commercial farmers point of view.
A commercial farmer is going to run trails to learn what his chosen cultivars and culture method do. And then tweak and tailor nutrient levels and application rates dependant on plant development stage until he finds a happy place.
If you are doing small freshly rooted clones straight to 12/12, I think there is no time for this. Better to stick with a general purpose formulation.
I can buy a few broiler chicks and raise them with kitchen scraps, and bit of ground/crushed maize. They will grow into big tasty birds.
Or I can fill a shed with thousands of chicks and buy in a protein rich concentrate. And use various ratios of concentrate to ground maize, depending on age and stage of growth. They will grow into big tasty birds.
I think that you have to tailor your NPK regimen according to how they are performing. Just remember there are guys growing with tomato fertiliser costing pennies from the dollar store. And in a blind test the average person would not know the difference when sampling the cured product.
Then there are the guys with multiple bottles of nutrients, additives and "boosters". They end up with identical product to the guy using tomato fertiliser or Jacks. But feel better because they spent more money and it must be right.
Or you can grow organic. And for sure organic chicken tastes better. But weed, we just burn it anyway.
Where I am, the average consumer wouldn't know. They used to the same generic rubbish cultivar thats been passed around since early 2000's, and wouldn't be able to appreciate superiour tasting bud. Granted, it is powerful. But so souless. The only way some people would recognise alternative good product is if it dropped its panties and said, "Hello".

just rying to get the picture and hope to learn some of him.
it really seems he recommend 20-10-20, EC 1.3 all the way through, much more N and quite low P compared to most bloom formulas.
maybe one day he go a bit deeper there and explain his thoughts.
basically it is no problem to tailor the nutrient regime, as long there is some guideline, sadly there are a lot guidelines out there some higher some lower in N during flower.
cost of fertilizers are non issue, myself is using salt which is even cheaper then jacks, 4 bucks a kilo dry fert, 25 bucks for 5 kilo or so.
so its no big deal to play around there, while i would a prefer a as simple as it can be aproach.
what does have a impact on the yield is the ammonia to nitrate ratio.
thats no secret, hydro tomato growers have bigger yields avoiding ammonia, at least there are studies showing this.
otherwise i dont beleive much in snake oils either.

been trying to figure out if he does use 2-1-2 from veg to flowering as well :\
