Ph + Ph - Help

[Ekko1029]

Hi, I bought a product to raise and lower the pH (Advanced Hydroponics of Holland + -) however it doesn't seem to be working, the ph is always the same...I used it in the soil mixed with water (ph 6)

these are my answers:

can be used in soil?
can be used mixed only with water instead of water+nutrients?
which is the exact procedure to use this product, why is not working?

water
calmag
ph+-, stirr well, let sit
fert, (s.o.)
fertigate
profit?!

What pH tester do you have? What is your precise procedure for testing pH?

It's not going to change ph of soil.
You use it to adjust water, and feed ph.

Got a link to it, Advanced hydroponics is a UK shop I couldn't see the product?

i tried with 2 different tester and now im gonna try with litmus paper

I use aquarium drop test kit to check ph.

yeah very similar to litmus paper, i think is the same thing

 

[lime73]

Have you calibrated ph pen prior to using it?
I dont like them personally, my drops kit works, where a digital machine is not always correct. especially if not calibrated properly, can be way off, thays why I use drops, more reliable imo.

do you use that kit for soil?

 

[lime73]

I use it for the water. Adjust water for my soil grow yes. But it wont work to test the soil ph, You need a different kit for that. Slurry test kit, or get a soil ph probe.

as I thought.

Did you say your water pH is six? That's good for soil.

 

[Ekko1029]

ok the problem was the ph meter...the product is ok,resolved with litmus paper...they can be used to test the soil too

I have never had to use pH plus yet only pH minus.

I definitely wouldn’t do it in that order.

The bloom nutes I use would drop the pH an additional point... so if I pH’ed to 6.0 before adding my nutes, I’d be at 5.0 or lower.

Add all your shit, then PH. Your plants care about the pH they get, not the pH before you add pH-altering nutrients.

no just changing the order in which you put your ingredients into the bucket is not going to make the solution more acidic than before. I never suggested to pH to 6.0, now did I?
PH acid needs to work on CalMag/chalk or it may destroy the mico nute chelates.

Adjusting pH before you add base nutrients is mad and chasing a target that is about to move. If that’s what you suggest, I disagree. Base nutrients significantly change pH. water, then calmag if needed, then base nutes, then allow a rest and adjust pH.

Any other way is inaccurate. Sorry.
