PH, EC, PPM, CF help

[BooMtoLate]

So I received this new meter and I threw it in my res and here’s my reading

Ph 5.7
Ec 3.24
Ppm 2270

Growing in coco and hydro stones and autopots with 47l res. Im first week of flower and the numbers seems high. I’m feeding them advanced nutes as per there calculator and the grow seems fine. Although the numbers seem really high to me from what I’ve seen looking around. Anyone have an insight?

Did you calibrate your meter before use?

 

[BooMtoLate]

It came calibrated but I just did it now, numbers read slightly higher now lol

 

[Hydroholic]

You calibrate at 2 points or just 1?

 

[BooMtoLate]

Sorry what’s that mean?

 

[Hydroholic]

Did you only calibrate at 7 or did you do 4 and 10?

 

[BooMtoLate]

I did all of them and calibrated Ec as well

 

[BooMtoLate]

I use sensi coco bloom a & b
B52
Voodoo juice
Tarantula
Calmag
Bud candy
And ph down

my tap water is sitting at 660 ppm and ph of 7.8ish.

 

[Hydroholic]

I never had numbers that high with my AN. Are you using faucet or RO water?

 

[BooMtoLate]

Googling now and 660 ppm tap water is crazy. Meter must be fudged or I’m as smart as a tree stump

 

[Hydroholic]

That’s where the extra is coming from. Your water. How long have you been at this mix?

 

[Hydroholic]

My well water was 450. I went RO for better control in hydro.

 

[BooMtoLate]

I’ve been running the nutes and water since the start and plants seem fine. I’m due to change the water in a few days. I’ll give RO a go

I’ve only ever measured ph cause that’s all I had was a ph pen. Know I got this new unit.
