Issues i can't seem to figure out please help

1.9 would be something like 1600ppm im guessing

No on a 700 scale its 1330ppm. I have a bran new bluelabs guardian monitor that u can switch between ec, and ppm on 500 or 700 scale and when i have it on the 700 scale it reads 1330 ppm and switch to ec it reads 1.9

did you put it into a calibration solution to see if it reads close to what the solution is?

No but i will when i get home in about 45 min

I double checked it against hydro buddy (another calculator)
it says your EC is 0.9 for bloom

oops soory for the double post

it says your EC for your veg mix is EC 1.0

Ok just checked it and its dead on with the calibration solution

Not sure if maybe the fact that im using ro water makes a difference?

Been having some major issues for a little while now that i cant seem to get a handle on. I am in week 5 of flower and things just look like shit if u ask me. Leaves have been dieing off yellowing and all sorts as well as slow flower growth. Ph has been keeped between 5.8-6.3 and ec of 1.2 using maxibloom. Here are some pics

I know it's different media and nutes but my first grow my plants did the very same thing. I game them nutrients, not too much water but still kept getting yellow and dying leaves. I'm not sure if this is true but the ladies will take nutrients from the leaves to help assist the the flower production. It will start to eat itself. If there isn't enough nutes. Some people welcome this so all the nutrients get used up and flushing at the end seems easier. Those guys were a bit advanced and knew what to look for.

Thats not the case, i definitely have a definitely issue in which i believe its just imbalances in my nutes. This started way way to early to be what your talking about but thanks.

if your EC pen is giving you bonk readings that would be an issue

you think your feeding EC 1.2 but really only feeding 0.7

RO water only makes me more sure

your working with virtually zero ppm water to start

if you had well water or tap water and had high EC I might think the tap water EC is adding to your mix

but the RO water adds about nothing

Yeah i get what your saying but when i checked it with the 1500ppm calibration solution it was right. So im not real sure y its at 1.9ec if it should be at 1.0 doesn't make a lot of since lol

I have a hanna monitor as well i will take it in there and check it against the bluelabs and see what i get in just a few

Ok so just double checked by putting my hanna meter in the solution and it read the same at 1330 ppm which comes out to 1.9ec
