How to read my EC/TDS meter?

[spider_b]

I run EC 1.2  through my grow I might up it to 1.4 as the buds start to really stack 

[Naycha]

hmmm i only have 946 ppm....

 

so does that mean more nutes?

 

im a total beginner with this stuff, have gotten 4 weeks through vege now and havnt used any PH or EC meters and everthing looks healthy, just curious as to how to keep my EC and PH in good order

 

My bore water i use is 6.0-6.1Ph  and at 162ppm

 

If you want to use the ppm scale you need to know which ppm scale your instrument displays in.

 

My Bluelab Truncheon displays both; ppm = EC x 500, and; ppm = EC x 700.

 

The common scale used in hydroponics from what I've seen on the forum and read on nutrient bottles is millisiemens (mS). So when someone says they run a particular 'EC' they are generally referring to EC measured in mS as EC isn't a scale but rather a description of what you are measuring.

 

eg. an EC of 1.0 mS is equal to 500ppm (ppm = EC (mS) x 500)

Hey qwobbler what make of EC-Meter do you have ????.

[Qwobbler]

its this one

 

 

it measures in: mS, uS, ppt, ppm

 

it says its callibrated to 1413uS (700ppm)

[Qwobbler]

ok so really i only need to use the mS measurement as its the same as EC....?

That's rite qwobbler even if you  have a dot in between the 2 numbers it mean's the same measurement,Eg={22 EC,or 2.2  mS mean's the same.

 

If you are not still to sure on what you are doing just google it an you will see what we all mean an are trying to tell you.

 

Have you got some calibration fluid to calibrate your EC meter with.

 

An if that meter ever shit's it self buy a Blue Lab truncheon EC/CF/PPM/ Meter next time they cost a few dollar's more but they are auto calibrated from new at the factory so you never have to piss around calibrating them an they are one of the best around an they stand by there warranty an don't mess you around with the warranty,I had to do a claim on a blue lab EC-meter about 6 months after I brought it an it took only 6 days an I had a new one to replace the other faulty one all air/mailed to me at no cost to W.A.  from New Zealand that's top class service in my book's.

Hey qwobbler I ment to tell you to wash your probe end of the meter in fresh water every time after you use it that way you will help to stop any salts from  forming on the probes an you will get a correct reading every time.

 

Plus calibrate your meter every month just to make sure it is adjusted correctly.

cheers mate, think i got it figured now.... i hate google, there a millions answers for 1 thing all the time

 

i dont have any calibration solution but it says its calibrated from the factory...

[Qwobbler]

now my ph is up to 6.2 and mS is 1.9

 

why has this happened?

 

what to do to fix it?

 

my plants look happy, but maybe its why its prelonging the flowing on my Big Bang auto flowers? they are at 5 weeks with no pre flowers, just little clumps ready to burst..

 

im still on vege nutes, did rez change yesterday
