My formula (Bloom) is this:

N (NO3-) 115.853 5.3% +/- 0%
K 172.903 -1.2% +/- 0%
P 67.648 4.1% +/- 0%
Mg 50 0% +/- 0%
Ca 120.91 -3.3% +/- 0%
S 67.74 -3.2% +/- 0%
Fe 2 0% +/- 0%
Zn 1.2 0% +/- 0%
B 0.4 0% +/- 0%
Cu 0.6 0% +/- 0%
Mo 0.06 0% +/- 0.6%
Na 0.454 0% +/- 0%
Si 0 0% +/- 0%
Cl 0 0% +/- 0%
Mn 1.5 0% +/- 0%
N (NH4+) 0 0% +/- 0%

I think you add a little extra salt with out knowing, maybe you where too high lol that happened to me lol. My numbers are a little higher than yours for my all around formula plus I add sucanat and Fulvic acid to part B and my ec is 1.8 (1255ppm @ 700)

Also Ca should be equal to a little lower than N. P should be equal to half of S and around a third of N. K should be double Ca. Mg should be half to a third of Ca.
I use this numbers to veg in coco and flower in a LP aeroponic (stinkbud rails)
N 144
P 56
K 199
Ca 120
Mg 50
S 66
Fe 3
Zn .4
B .3
Mn 1
Cu .2
Mo .08

Good luck and happy growing

@cobshopgrow and @TintEastwood
You guys seem to know a lot about all these ingredients.
Now I have a question and perhaps you guys can help me out.
It is about P2O5.

In all fertilizers P is always named as P2O5 on the label. There are several other names for this: Phosphoricanhydride and Phosphourus Pentoxide for eaxmaple.

Canna has for example a Mononutrient called Phosphor (P2O5)
In the description it says: This mineral fertiliser contains 20% P2O5.

Now Canna also has pH - Bloom.
Here it says: Contains 41% phosphoricanhydride (P2O5)

Now I know all those nute firms make us pay more for a very common product.
But is there, apart from the concentration and price, any difference in the Mononutrient and the pH- Bloom?

Took a look at the products, but not sure if same ingredient. Chemical stuff a bit over my head!

Interesting. The "ph bloom" is a ph down product that seems to be based on the phos/P205. Most are potassium based, I think. Canna has a lot going on. Solid company.

i am not firm with all forms of phosphor, but have some thought.

P2O5 descirbe how much P is in oxyde from in the fertilizer, it doesnt tell us anything about the source.
P is the elemental, really avaiable PPM for the plant.
20% P2O5 are 8,74% elemental P.

Am sure you know all these allready, but cant be mentioned often enough.

the differences between their mono nutirent and the PH- is probably that the PH- is Phosphoric Acid and you probably cant/wont apply too much?
Phosphoricanhydride and Phosphourus Pentoxide are both forming acid it seems.


these Canna "Mono" nutrients are a miracle to me.
they dont list whats in them.
in nature pure, mono forms are seldom, real seldom.

f.e. google the safety Datasheet of the Wuxal Calcium fertilizer if you want.
they just list the calcium on the bottle.while beeing made from calciumchloride.
i think the canna mono calcium is similar,/same, just a guess? or calcium sulfate?

chelated calcium isnt avaiable since so long, and canna momo calcium is, 20y old at least.

havent digged deep in to their P mono and what it can be made of.
as we all know PK boosters are often MKP, there you have the P and the K as chemical element., while this is their PK13/14.

the canna magnesium mono will be prob. epsom salt, magnesium sulfate., you get the sheme.

its a bit edging my knowledge too,

i just want to point out, that there will be prob often 2 elements together, "Mono" is misleading, or its a carbonate or a acid, but then it influence your PH quite heavy.
