I am currently experimenting with adding nutrients to my current base formula of Advanced Nutrients Bloom, Grow, and Micro. I know the optimal NPK values for growing cannabis (pic related) but i want to know how far i can specifically go with it. For example, my base nutrients have a combined NPK level of 4-3-8. How high can I let the NPK level get by adding other nutrients?

It’s actually much more important to know the Electrical Conductivity of your nutrient solution, in the case of your question.

I am interested to hear what the “optimal” NPK ratio for cannabis are. Since you “know” the answer, please share it wih all of us who are just guessing.

I don’t see any picture to which I can apply a relationship.

In veg you want high levels nitrogen, medium levels phosphorus, and high levels of potassium
In flower you want low levels of nitrogen, medium to high levels of phosphorus, and high levels of potassium

What do you mean how high the NPK level can go?

There is no such thing as level...there is only ratio therefore if you are happy with 4-3-8 then stick to that ratio, which simply means 4 part Nitrogen, 3 part Phosphorous, and 8 part Potassium.

There are many ratio's. Such as 1-1-2
or you can go crazy like random ratio 50-1-100. You can dump an entire bag of Nitrogen to 1 tsp of phosphorous, to 1 tbs of potassium....its still called a ratio.

But I think you're confusing Volume or PPM with NPK or the other measurement EC which Michael have pointed out.

Seriously, lets take your NPK ratio of 4-3-8

example;
4 tsp of N, 3 tsp of P, 8 tsp of K
4 pounds of N, 3 pounds of P, 8 pounds of K

Both have the same ratio of 4-3-8

The difference between the two is in volume or
if you gonna mix those in water you have PPM or EC

So having a ratio of something crazy like 50-1-100 isnt going to hurt the plant?

That was meant as an example. You can use that ratio or any ratio for that matter. Havent heard anybody using that kind of ratio either :bigjoint:

When you make a ratio, you start from smallest denomination (or part). In your 4-3-8, its 3...in my crazy example 50-1-100, its 1.

More ratio example

1-1-2

is the same as saying

2-2-4
or
50-50-100
or
25-25-50

your 4-3-8

is the same as the following

12-9-24
20-15-40
