not the nutrients themselves.

any thoughts?

NPK Ratios are not as important as Poeple think they are. Canna Coco is 5-4-3, Canna Cogr Flores is 3-3-7, both work fine on any Coco Medium.

Actually you are correct its not the Nutrients themselves but how Poeple use them in Conjunction with lots of different Additives that they got Suckered into buying.

Understanding basic Fertilizer Chemistry is really not that complicated. Once Poeple have that Knowledge they should be able to clearly see beyond the Marketing.

Ummm no but only up to a certain point.

Bingo!!

Most cannabis growers have no clue what nutrient solution profile they are running. Farmers know exactly how many ppms of each nutrient they feeding their plants. Cannabis growers talk of NPK in terms of numbers like a 5-2-6 and rarely delve into those numbers with any substantial meaning.

For example here is the nutrient solution profile for H3ad's 6/9 coco formula.
N 97
P 60
K 105
Ca 97
Mg 41
S 27

Most people gloss over the solution profile numbers and only focus on the "6/9". Understanding your solution profile and how those chemicals work together or against each other is very important in figuring out how to get the most out of a cannabis plant.

Impossible to get anything decent running more K than Ca. Absurd.

Who would run more Ca then K in anything but your Mythical Soil?

Poeple think Jacks has too much K with its 26%, i run a 36% Mix and have no Ca Issues at around 2:1 K/Ca Ratio, in Coco.

After a while of feeding theres so much Phosphate Binding in any given Substrate that what you think you are feeding isnt what Plants have actually availible for them.

AD,

How about the University of Florida for one? Even then, it still needs more Ca. A couple of the guys are running even higher Ca using a good chelate and it is much better than the Univ of Florida attempts. Of course you can't get close to the ratios needed in the "mythical soil". That is what makes hydro so lousy. Hydro looks great, often smells great, but the terps, oils, yields and at the end of the day, smoking quality, aren't there IMHO.

Sounds like you need to understand electrical charges a bit more. This crop will tolerate a lot, that is quite evident and if you see issues, well, you missed the boat anyways. Saying you don't see issues doesn't mean much. If you EVER have a calcium deficiency, there is NO catching up. So far, EVERYONE has had a calcium deficiency!

What credentials have you got?

It's unwise to think that Osmosis will bring you the results you desire. Luxary compensation is a Faux Par.
Your past sentences answer all our future questions for you. Your time here is done. Your lack of an understanding shows from post 1. You have no images to back up outlandish claims & no scientific basis to your argument.

Ratios are everything, even though much of the agriculture community (specifically the potassium and phosphorus institute) would have you think otherwise. Just think how much more K they sell than folks need! Read up on the concept of SAR (sodium absorbtion ratio) and then tell me ratios don't matter. This is the most basic of basic principles.

Ratio science was done years ago by Dr. Tiedjens. I posted a page somewhere where you can download his book for free. Read it. Several times.

Excellent post!

What outlandish claims exactly? Maybe i can provide a Link and pretty Pictures
