If veg NPK is 3-1-2 then wtf are most nutes no where near?

I was under the impression that a decent vegetative NPK for marijuana was 3-1-2 whereby nitrogen is the main ingredient, even 2-1-1 / 3-1-1 is recomended....

So why is Canna, Ghe, Ionic, Biobizz and most others so far from this basic ratio, some even have ratios like 4-3-7 and so forth.

Maybe its just me but these numbers dont even seem to be in the ball park for Marijuwana....

Hi. I guess it is depends on growing cycle. Plant needs much nitrogen in veg stage and calcium in flowering stage.

The numbers just represent the percentage of the nutrient content in the mix. Doesn't stand for concentration or anything like that. You can use a 20-20-20 and get perfect results.

What you're looking for is how fast it's processed and how long it takes to break down. At least I think that's the info you're looking for.

Not what im asking and wether 20-20-20 or 2-2-2 its the ratio im more concerned with not the strength. A veg nute of 30-10-20 is technically the same as a 3-1-2 in my eyes as they will both be mixed to the same PPM by me.

True plants need most nitrogen in veg stage but some of these fert companies seem to be supplying more potassium than nitrogen in the veg stage, check out Cannas NPK.


I dont find that a general purpose fert is good for the veg stage, 20-20-20 is not high enough in Nitrogen whereas a 3-1-2 is a lot higher in Nitrogen i.e. 3x the amount of Nitrogen to Phosphorus and a third more than Potassium by ratio.

I understand that. What I'm trying to tell you is that not all nutrients are created equal. Just because that nute says 4-1-3, doesn't mean you can't have a nitrogen deficiency. What good is it if it burns itself out in a short amount of time?

In other words, you should be more concerned about the nutrient content and work the ratio out afterwards if you are looking to get the most from your fertilizer with the least amount of problems.

Canna Terra Vega - Cannas soil fertilizer for veg

Npk = 3-1-4

Listed as containing more Potassium than Nitrogen, why would i need that much Potassium in veg!

You wouldn't, so why would you use it in veg lol?

The ingredient for they're potassium could be at 2% strength. More potassium content, less actual nutrition. Get it? The nitrogen could be at 20% strength when it's listed as 2-9-4. Go ahead and add that to a flowering plant because the ratio looks good. It'll jack your shit up.

Think alcohol percentage. 8oz of 5% alcohol is lesser than 4oz of 40% alcohol... Even at a 2:1 ratio. Hope that makes sense.

I use 3-2-4 in bloom. They seem to like it.

That would be a veg Npk not bloom in my local hydro store, beginning to get suspect about these 'Marijuana SPECIFIC' ferts.

I fear that im following nute companies because they should know better but fastly realizing that they dont have a clue.

They're all within the ballpark of marijuwana; Botanicare, Advanced, GH, Dyna-Gro, Canna, H&G, Blue Planet, Espoma, Miracle-Gro, amended soil -- it doesn't matter. Cannabis isn't a picky eater and it performs great with many NPK ratios. The key is dialing it in for your particular setup and style of growing.

Are you talking about Potassium because most list that by its solubility in water/citric acid ie. K20 percentage.

Im not sure if your overcomplicating things as i just work of general NPK of which there are certain standardization.

It's any bottled nutes. Let me try to simplify this.

For example, NPK ratio of 3-3-3. That means that 3% of the volume is N, 3% is P, 3% is K and 92% is filler.

Now, your 3% N is broken down into concentration. The nitrogen concentration in that 3% could be 100% or 80% or whatever they chose to go with.

In other words, ratios are just how much content is in the mix. Concentration is how strong the nutrient in the ratio is.

You sure because some top growers recomend Nitrogen to be higher than potassium and many recomend dyna gro but only the foliage pro for veg which is an exact 3-1-2 ratio. Uncle ben seems to swear by these Npk's and has issues with the more Cannabis spexific npk ratios.

This is me dialling it in hopefully.
