how do I get n-p-k in ppm individually?

[little-soldier]

sup guys,
my FloraNova Bloom bottle reads 4-8-7 (N-P-K)
It says on the bottle that 2.5ml per gallon will give me 300ppm
Now my question is how can I calculate how much ppm n-p-k has individually if my truncheon reads 300ppm assuming that my waters ppm is at 0?
what I need here is the formula so I can do the math myself so if you have a link to advance nutrients calculator, It is not what I am looking for
thx

Still 19X=300.

4X=N
8X=P
7X=K or
19X=300

i tried asking this same question a few years ago here.
got the same angelfire link too.
i still cant figure it out either, i must be retarded.
thats why i went organic,
its easier on the brain

so lemme get this straight:
Still 19X=300.

4X=N
8X=P
7X=K or
19X=300
4-8-7 @ (roughly) 15 mil/gallon would make 300ppm?

you simply take the ratio x's ml/gallon to figure your ppm's
can it be that simple?

 

[FreezerBoy]

The whole is equal to the sum of it's parts.

Note that 19x refers only to the ingrediants supplied in the post and assumes 0 ppm water, no pH up or down, no additives of any kind, no micro nutes .... I dont use FloraNova but would be VERY surprised it it contained npk and nothing else. Where's the Calcium? Magnesium? Mangenese? Sulpher...?

In my case, with my nutes and my water, the formula would be 26.6513X= 0.1. (Because ppm is babble I've substituted a meaningful number in the form of EC. In the above formula, ppm is considered to be ECx500 rather than ECx640 or ECx700)

I have been completly lost on the whole ppm and ec for a while now, and i so use nutes, bc bloom to be exact and never had a problem w/ my plants using about 1/3 strength, but in order to maximize my yield i need to learn. What are some good links to for me to figure all this out?

 

[FreezerBoy]

EC, CF, PPM and TDS all measure strength of solution. CF, PPM and TDS are all EC x: a silly number, a meaningless number, or a number too stupid to live and thus, mangled into meaningless babble. EC is the one number the world agrees on and requires no conversion.

If EC rises and pH drops, your solution is too strong (you're drinking water leaving food behind)

If EC drops and pH climbs, your solution is too weak (you're eating food leaving water behind)

The formulas on the bottles are a general starting point. But no one formula is going to max out all varieties. With an EC meter, you can zero in on your particular needs. While I'm glad I have one, now that I do, I wonder if I really needed it. It's possible you could figure it out on pH readings alone. I could buy cases of pH test kits for the price of one BlueLab EC Truncheon.

 

[dkmonk]

Okay thank you, so just monitering my ph will be sufficient enough. I just didnt know if i was losing out a lot on taste and yield because i wasnt paying attention to EC. I usually just feed my plants a little amount and go up from that, if they dont get nute burn then i add a lil more next time and find the right amount for the strain im growing.

(10xN/P/K)÷(conversion factor) = ppm

EC, CF, PPM and TDS all measure strength of solution. CF, PPM and TDS are all EC x: a silly number, a meaningless number, or a number too stupid to live

It's not hard to convert once you have the formula, Personally I prefer ppm to EC as I can tell at a glance whether my nutrient solution is between say 0.8 and 0.9 ec, I can tell if it's 0.86 for example (which would most likely appear as 0.9ec on most ec meters) since I know my conversion factor is .768 I can draught a simple conversion list..

EC-PPM @ .768 conversion
0.1=76 (or 77 rounded up)
0.2=153
0.3=230
0.4=307
0.5=384
0.6=460
0.7=537
0.8=614
0.9=691
1.0=768
1.1=844
1.2=921
1.3=998
1.4=1075
1.5=1228
1.6=1305
1.7=1382
1.8=1459
1.9=1536
2.0=1612

Basically ppm imo is more accurate.

my FloraNova Bloom bottle reads 4-8-7 (N-P-K)
It says on the bottle that 2.5ml per gallon will give me 300ppm

4x10÷0.768=62
8x10÷0.768=125
7x10÷0.768=109
^^296ppm

But always check with a meter!

thank you pimp aurora
K+++ for you.

It may be easy yet I note many of your numbers are wrong. Seems silly to multiply everything by a meaningless number just to come up with the wrong answer. The trouble with ppm is no one agrees if it means x500 or x640 or x700. You're a perfect example. You insist it's x768.

If we stick to the original formula, 19X=300 we find
N=63
P=126
K=111
Total=300. By avoiding imaginary numbers we get a more accurate answer.

However, he's still not going to get an actual percentage unless he includes the other ingrediants I suspect are in there.

How are conversion factors imaginary numbers? they are different because of different factors for different countrys, I see no sence in your method personally, maybe I need reading glasses but you're numbers don't seem to add up either let alone make any sence.

19X=300 Means what exactly?

I downloaded a handy little calculator, spreadsheet program called Nutrisolve off OG a few years back...pretty handy if your looking to hit specific numbers.

....edited for snarkiness....

Let's try it this way

Farmer John sold 4 white cows, 8 brown cows and 7 spotted cows for $300. How much did Farmer John recieve per cow? How much for the white cows? How much for the brown cows? How much for the spotted cows?

Farmer John recieved $15.79 per cow (19X=300, X=15.78947368421)
Farmer John recieved $63.16 for the 4 white cows (4X)
Farmer John recieved $126.32 for the 8 brown cows (8X)
Farmer John recieved $110.53 for the 7 spotted cows (7X)

Total $300.01 (because we rounded off X. Had we used X at full strength, the 1 gets pushed right at least six places)

Your just weird.
Maybe if you told us your imaginary number "X=15.78947368421" at the start it might have made sence but don't be a dick and talk to people like they're 5 years old. go learn how to tell the colour of your trichomes, you still can't after 14 years, your a joke to the growing world.

 

[FreezerBoy]

There's nothing imaginary about X=15.78947368421. The question was how to determine 1/19 of 300. The formula was, is and shall remain 19X=300. I did, in fact, explain it at the start; Twice.

Trichs have nothing to do with this but, way to change from a subject you know nothing about to one you understand even less by lying.

You have my sympathies, that your youth was spent without one on whose knee you might sit and thus learn the lessons of common civility and honesty or, to send you to school that you might discover the wonders of language and math.

- Ammoniacal Nitrogen: 0.25%

Now we're getting somewhere. For FloraNova Bloom the formula is 27.1X=Strength of nutrient solution.
