Cannabis feed causing very low 2.0 ph water feed

Hi my first feed of Dutch pro bloom 100ml of a and b each in 50 litre is giving a ph reading of 2.1. Is this normal? And I’ve been grow shop to purchase ph up and had to use a cap full to bring it back up to 6.2ph so I’m not sure if that is too much too use either. Thanks

Have you calibrated your ph meter lately? I haven’t used that brand but that ph sounds crazy low.

Yeah brand new ph pen calibrated correctly and tested with an old one that still works

Something is drastically wrong there.

my pH of source water was 7.4.

when I used to use DP bloom (I only use the grow formula now) it only dropped pH to 6.9.

Do you have anything besides a meter to test your pH? Litmus paper? Dropper kit?

Seems rather off to be dropping to 2.1 as anything below 4pH and you start getting precipitation of the nutrient ions falling out of solution.

Not normal.

2.0 pH is vinegar. There is no way you're lowering the pH that much by adding Dutch Pro Bloom A + B. In fact the bloom should likely raise the pH not lower it. edited

Either both your ph pens are wrong, you're not calibrating them correctly, or you have mislabeled product. If it was that low it would take more than a capful of pH up to bring 50 liters up to 6.2.

They make a pH- Bloom which is 30% phosphoric acid. If you used 100 ml of it in 50 liters it could lower your pH that much. What do your labels say?

I’ve just poured some Dutch pro over my hands and it started tingling sore. Think I’ve been ripped off by amazon seller with good reviews. Feed have probably been used already and refilled with fucking battery acid the cunts

I have eczema and the grow formula tingles my hands.

I haven’t a clue then I fed them with the feed and ph up and I can tell something’s wrong as the soil is still damp they usually bone dry after 36 hours and the run off was 4.4ph after a flush to clear and some leaf tips have started going dry crispy

Double checked compared with new Dutch pro from grow shop and the one from amazon must be fake product ph of 0.4 where as the grow shop product has ph of 4.1.Messaged the company they said they only buy Dutch pro products from Dutch pro company. Obviously full of shit or selling out of date feed

Wow can't believe that,
I almost want to stop buying nutes on amazon now

What is the link you bought from?

NOBODY asked the right question!

What is the source of the water? How many ppm's are in the water if you meter that?
I'll bet it's very, very low.

You see, the less mineral content of the water. The less ability it has to "hold" a pH value. With many nutrient lines making low ppm water drop in pH is actually rather normal.
More so for bottled organic nute lines.
Even things based in organic sourcing will make big drops in pH after mixing, normal also.

Adding an amendment to Low pH mix's is a way for the mix to stabilize (so to speak) and hold at the desired higher pH.

In Hydroponics and use of RO. You must add Ca/Mg back to it for the plant and it also helps with that "pH stabilizing" thing.

If you didn't, you would notice your pH fluctuating too much, to often.
