AN Grow A+B PPM please help

[Ranman60]

I have a new Blue Labs Guardian Monitor meter, it's very nice, really liking it.
But not sure if I'm doing it right.

Ok, I have well water with a ppm of 120.
Verified with a ph pen and the blue labs monitor.

mix
1 liter of well water
4 ml of AN sensi grow A
4 ml of AN sensi grow B
2 ml of B52
2 ml of Voodoo Juice
And I get a 1800 -1850 ppm reading
Is this right ?
Spoke with AN on phone said should be around 1200 ppm
I mixed this 3x and all about the same 1800-1850 ppm
I need to know what full strength is in Ppm
Thanks

To add on, I took the packet of 1940 ppm test solution and tested the blue lab meter and it was spot on.
Thanks

I can 100% promise you AN didn't tell you what meter conversion rate they were basing this on.

There are two basic meter conversion rates.

One meter uses .500 conversion, while the other uses .700 conversion.

If you divide your 1800 by 700, you get 2.4 e.c.
If you divide 1200 ppm by .500 you get 2.4 e.c.

Both give the same result, but on your meter they read differently because they use a different conversion method. It's the worst thing about AN and giving ppm's. They don't tell you this extremely important aspect.

Looks to me like you have the mix exactly where they said to put it. But you're using a .700 conversion meter vs their .500 conversion.
