What's your late flower nutrient regimen?

[Hiddenjems]

It's amazing how an industry has convinced so many people that they need all these unnecessary products and a feed chart on how to use them. Cannabis specific nutrients are nothing but a massive scam. Fortunately there are billions to be made marketing this nonsense to a bunch of stoners that don't know any better. They're too busy regurgitating stories they heard from some dude online they've never met and arguing about the origin of OG Kush to realize they're being ripped off.

You can pretty much feed any cannabis plant jacks and calcium nitrate in the same ratio beginning to end. If you want less n and more pk during flower for whatever reason don’t buy any of the bloom boosters, just change your ratio and ec. Why buy overpriced chemicals THAT YOU ALREADY HAVE?

I use it for seeds, clones, vegging and flower.

In each of the 5 tables, only two lines really matter. We have the Uni guidance and the growers actual average.

N dropping through bloom
P dropping
K dropping in the uni guidance, but increased by growers
Ca steady
Mg steady in the guideance, dropping by growers

As averages from a large survey including field growers, the numbers still need a bit more thought. They do give an idea what people are doing though.

These charts are still produced each year I imagine. With a little talk about trends over the years. Lowering P is a known trend over recent years. 30ppm is low, but 80% of yield potential is possible still. Doubling P input might not be financially valid, but for the home grower, 60ppm is likely the right number. 90ppm is likely to start reducing yields. I'm talking available P though, and many fields are using organic sources that might not actually become available at all. The Uni numbers are hydro.

GH has late bloom fert without N in it, only P and K ..i haven't used it myself thou
GH FloraPro Late Bloom


- One way to cut N level of a single-part bloom fert is to use a PK 13/14 product to replace some of the N rich fert

i was today years old when i found out gh have late bloom formulas.... it's the only line i've ran in dwc. i typically just stick with their trio and a bit of koolbloom and floralicious during flower.

Excellent, do you have a link for me to that article Ca++ ?

Edit... I found it.... thanksss.

Heads up though, I'm pretty sure the new GH flora pro grow, bloom, and late bloom dry mixes are missing the needed micros that are only added into their version of calnit\part b. You can't just use other brands of calnit you might already have with it, and basically forced to buy their "calcium + micro" part b product to go along with it, and keep the proper ratios.. as far as I know anyway.

I didn't see that stuff, either. Depending on your flowering philosophy, that stuff has wayyy too much P in it.
I got me a Cropsalt kit and it has been working great. I'm keeping it at pretty much factory recommends, based on if my cultivars burn or not at recommendations. It has a decent amount of P for the few weeks you use it in bulk phase flowering, then you switch to their finisher called "cake". Cake has none of that stuff. In fact they give you the bare minimum info that laws force them to, and the rest is a mystery.

 

[Hiddenjems]

Cropsalt is just another company exploiting cannabis growers with a huge Markup on cheap salts and lots of products to buy.

A few runs with either Lucas straight through or jacks straight through gives you a solid base to judge from. I’ve never seen anything without pgr’s produce better.

A perfect environment and co2 at 1400ppm with jacks has produced my best harvests. Co2 costs me around $30 a week for a large room.

 

[membersonly]

Farmers pride bloom in late flower has been my favorite. Drops nitrogen and micro but also has guano, molasses , rock phosphate, mkp. Good stuff.

 

[420empire]

A simple box with a filter inside will prevent any dust, pollen or mold spores from entering through the intake.

It is an entirely different matter when you open the tent.

Looks really nice.
Do you have a inline fan or is there enough power on your outake?
Cheers

 

[Worldatlas]

Im soils and organics.....past week 5-6 i dont give it anything but water to the sponge and let senesence get at it! These newer fluence/bios etc tend to require heavier feeds though that ive noticed almost dbl-to triple depending on the cannabis needs. Hope im not missing out on something.........

The exhaust is plenty powerful.

Veg regimen = early Bloom regimen = late bloom regimen

N is high in inflorescence, P also, and also is K. Higher than in most of the other parts.

Effect of Potassium (K) Supply on Cannabinoids, Terpenoids and Plant Function in Medical Cannabis

We have demonstrated in previous studies that the essential macro-nutrients nitrogen (N) and phosporous (P) have profound effects on the production of cannabinoids and terpenoids in the cannabis plant. The present study was undertaken to evaluate the hypothesis that potassium (K) supply, which...

[PadawanWarrior]

I'm in soil and stop adding N after the stretch. After that if I see P deficiency which is common, I add some bat guano. 0-7-0, 0-13-0, ect. Just added some to my closet of GG4 a couple waterings ago. I add micronutrients too a couple times during the grow.

I also push K and S as flowering goes on. Langbeinite has both but also has Mg. So I'll add some langbeinite midway if I think they want more Mg too, and potassium sulfate if I think they have plenty Mg.

Sometimes I feel like giving them a treat so I'll add some coconut powder to their water. They seem to like it.

Cool. Is it standard hepa? And what the size on the filter ?

HEPA have too high of a rating for me, MERV 17+, I’m using a MERV 9 whereas a MERV 7 would suffice. I figured the MERV 9 being rated for laboratory and hospital use would mean I’m getting slightly better filtration without sacrificing flow all that much. I’m using a 12” x 24” filter cut into a 12” x 12” filter.

I’ve been monitoring the intake quite a bit this second round, I even have a probe inside the intake filter housing to get the most accurate intake temperature and humidity readings. We have a 3°C increase on temperature and only 2% increase with humidity.
