Just Like Jacks isn't 3-2-1, MasterBlend isn't 2-2-1

Not 1 to .99 bro.

3-2-1 to 3.79 2.52 .99

The later is equivalent to 3-2-.64

That means they concluded that the original Mg was almost 2x than needed!

Do you have a link to the 3-2-.64

Not sure what you mean. If something weighs 3.79g and you only have one integer to represent it, it's usually 3 or 4. They are truncating the decimal in the first two numbers, rounding DOWN and rounding UP using decimal rounding in the last. Which makes it confusing. Again I really don't understand the npk numbers. I thought it was a weight number rounded to something. The OP is just stating those numbers are not close in precision. Basically only integer precision.

The numbers are weights…. Not the NPK… those same weights can equal different NPK ratios depending in the sources and wuality of the source nutrients used

Are you kidding 4 "or" 3. Since when has anyone ever rounded down from 3.79?

In math there are rounding methods that result in 3 from 3.79. It is why I said 3 or 4. Most things require the standard rounding rules which would be 4. I too use the more acurrate decimal rounding such as yourself.

But when you round up or down the weight of the dry salts from 3.79 grams per gallon of water to say 3 you have drastically changed the NKP Value of the solution. Even rounding from 3.79 to 4 is going to have an effect. Considering the antagonist relationship between P, CA and MG I would not play around with the weights.

While pondering math and physics, some consideration should also be given to marketing. In that case, it would make sense to truncate the first two to the integer, because people would like getting more than the label indicates. Then again, going from 0.99 to 1 is just easier.

I agree. This appears to be the logic.

I agree. It appears the actual NPK is only integer precision with no weight given to the decimals. For precise numbers, reading the label will be needed.

you are not getting it. 3.79 grams is not equal of a value of 3-7-9. or 4.0 or anything like that. It is 3.79 grams of Jacks 5-11-26, 2.52 grams of Calcium Nitrate and .99 grams of Magnesium Nitrate. These grams have nothing to do with the NPK values of the nutrient solution. Are you using some sort of translation application to change language

Thanks. I really don't know what npk means fully. Especially after this thread. I'll read up and be more informed.

So what should the npk value be of the example you listed?

NPK stands for Nitrogen, Phosphorus, and Potassium, which are three essential macronutrients that plants need in large quantities for proper growth and development. The NPK ratio is typically expressed as a set of three numbers, such as 10-5-5, which indicates the percentage of each nutrient present in a fertilizer.

To calculate the NPK ratio, you would first determine the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the fertilizer. For example, if a fertilizer contains 10% nitrogen, 5% phosphorus, and 5% potassium, the NPK ratio would be 10-5-5.

Examples of NPK ratios:

• 10-10-10
• 15-5-5
• 12-24-12
• 5-10-5
• 3-12-6

It is important to note that different plants have different needs for these nutrients at different growth stages. It's recommended to consult an expert or do research before using a specific NPK ratio.

Okay. I understand better now. It's a % by weight. Is this correct?

8 posts on this thread and you do not know a dam thing about what you are talking about. You are part of the reason why there is so much bro science about growing cannabis. Please understand what. you are posting before you post.

I only talked about rounding error. I immediately said I didn't know exactly what npk meant. I am anti bro science so not sure what you mean.

Also, please answer what the npk was supposed to be in your example. This whole thread started because of confusion on that exact example.

I am not going to teach you shit or help you in the slightest way shape or form It only took you about 5 posts to figure out there is more than rounding we are talking about. I played nice but I am done. Basically, if you post on a thread with information that is incorrect I am going to advise of your wrong ways and tell everyone not to listen to you. If you want to jump on a thread and you get 5 or 10 responses trying to get you to see the error in your ways and you just keep posting I will also tell people you have no idea what you are talking about. Just as you had no idea what NPK was but here it is you are setting right around 1000 posts. Sorry man but you need to do more listening and less talking because. you clearly do not understand what you think you understand.

 

[Habosabin]

So you can't take that last step and clarify that confusion for the whole thread? The OP said those numbers were off. Please enlighten us with the correct npk ratios. I admit I jumped in thinking it was a rounding error off the weight my mistake was they were percentages. With the understanding that it's a percentage I understand it. It doesn't appear to have complete information to calculate the npk based on those 3 weights.

I could do that and waste some more of my time. I say waste my time because that is what it would be a waste. You need to learn this stuff and me telling you the answer is not going to help you learn. You need to figure out how to retain the information so you can draw on your knowledge. Me telling you the answer means the information is going to go in one ear and right out the other.

 

[Habosabin]

But why deny the answer to the thread because you think I'm a dumbass? I didn't ask the question.

 

[Moshmen]

When J R Peters first launched the Jacks Nutrient Line the Ratio was 3 parts Jacks, 2 Parts Calcium Nitrate and 1 part Epson Salt. It has since changed to the current ratios.

Wow I thought the ratio is pretty clear ? The name is fir marketing purposes of course

I see exactly what you are. We see your type on the frame often. If you want to come over and do my dishes while I look up the answer sure I can do that or if you want to send me a portion of your crop for doing all the technical work for you we can arrange something like that.
I have seen your type around this forum more than once. You are the type that just wants someone else to tell them what they are doing wrong and get a quick answer. Cool. Go get your answer!!!!
