Is there any precedence for using bone meal for flowering cannabis!

It's usually a soil ammendment, so you would have to transplant before flowering,

but it supplies phosphorus and you have good soil funghi, so why not?

As a fertilizer, the N-P-K (Nitrogen-Phosphorus-Potassium) ratio of bone meal is generally 4-12-0, though some steamed bone meals have N-P-Ks of 1-13-0.

Bone meal is also an excellent source of calcium, but does not provide enough nitrogen to be beneficial to plants.

Plants can only get phosphorus from bone meal if the soil pH is below 7.0, according to recent Colorado State University research.

Organic fertilizers usually require the use of a variety of fungi in the soil to make the nutrients in the fertilizer bioavailable to the plant.

For plants needing phosphorus, the fungi mycorrhizae penetrate the root break down the compounds containing the phosphorus for easier absorption and utilization, and in turn the plants supply the mycorrhizae with amino acids and sugars.

In sterile potting soil, these fungi may not exist. Without these necessary fungi, which have a mutualistic relationship with the plants, plants could not utilize the needed nutrients in a high enough quantity for growth. Phosphorus, in particular, is needed for cell growth, as well as many other important functions.


While it has been long-believed that adding phosphorus to soils, as an amendment, "stimulates" root growth, in actuality it does not.

If phosphorus levels are too high, the plant will not excrete the necessary organic acids that are needed to attract and feed the mycorrhizae.

As a result, the plant will increase its root mass in an effort to compensate for the lack mycorrhizae at the expense of other plant tissues.

The calcium in bone meal can wreak havoc on plants if too much exists in the soil.

What about potassium? Don't ALL flowering nutes have copious amounts of K?

 

[Richard Richardson]

Not all

But go for Sulphate of potash, just to be sure...

The principal use of potassium sulfate is as a fertilizer. K2SO4 does not contain chloride, which can be harmful to some crops.

Potassium sulfate is preferred for these crops, which include tobacco and some fruits and vegetables. Crops that are less sensitive may still require potassium sulfate for optimal growth if the soil accumulates chloride from irrigation water

Really?, hmmmmm..........rico? I've only used 4 or 5 different kinds....but they all had a lot of it....the more high performace the product the more it had in it......

Massive Bloom has 1-1.5-2.8

Big Bud has 0-1-3

Most of the bloom boosters do have shitloads of P and K,

but in organic gardening, I think NPK values are secondary.

In organic, too much potassium messes up the mychos. The plant has more than it needs, so the root exudates don't feed the mychos properly, and mineral breakdown suffers. The ratios get screwed up.

With K, my understanding is go big or go home - ie, all NPK or no K at all - feed the plant OR feed the soil.

That's true, even wiki agrees

Thanks guys, I wonder how long it takes to break down.......I had never heard of giving it as a flowering nutrient....and I still wouldn't give it....for that.....I read about a hundred comments on other forums this morning....about using it as bloom food.

This is ricosan in her new home...she is doing some 'weight training".

That lady looks lovely Mac, but now I think you gave Rico a big head naming a plant in his honor lol! Moshi-Moshi Ricosan Konichiwa? LOL

Good Weed Day to you and Mrs. Mac, hope today finds your family well.

I named it after Puerto rico! Good weed to you sir!

Who's wiki, does he have a last name? I hear about him a lot, smart guy, knows everything you'd ever want to ask about. Must be popular! LOL!

Well Mac, in my 45 years it certainly wouldn't be the first nor last time I make an ass out of myself!

 

[Richard Richardson]

I used to have a small head, but then they named a country after me

My nutrient supplier says the same thing in organic keep the K below 2 so as not to kill the mycorrhiza. just validation

 

[Graytail]

(Thanks for the reps, guys!+)

 

[mcloadie]

She resisted at first.....I told her"you know mr squiryll, he lives on the hill by the sea in spain where the river burned in half in 72", " he has bendy round upsie turny doing it too!", she said" well shit, if he's doin it to them, you can do it to me, but it still hurts!".

Nah, I think she likes it - a new perspective, like when you were a kid and looked at the world upsidedown. Really, how many plants get to see the side of their own pot? Yeah? Huh? Pretty special, I'd say.

 

[Richard Richardson]

ohhh... that hurts.

But it feels sooo good

I don't believe this is true...my organic bloom food is 4-10-7, and it's loaded with mychos...............could it work differently with bone meal?

 

[Richard Richardson]

Mc, the nutrients from bonemeal are insoluble in water,

they have to be converted to a form that plants can use.

That's where the Mycos come in.

Bloom Fertilisers use different, soluble forms of phosphorus so the roots get it straight away.

My Bonemeal has NPK; 3.5%, 18%, 7.7%
