Hey A.Kslo , a Ph of 7/7.3 is too high check this :



If your Ph is too high it will block other nutrients , good Ph is 6.5 .
Is this an electronic Ph tester ? Try lowering the Ph of your water with some Ph down , do your nute mix , test Ph , and if it is too alkaline , add some Ph down and test again until you reach +/- 6.5 .

Thanks for answer, but

The thing is that ive been using Biobizz Light Mix, and thats and organic «soil» that should regulate the PH by it self. Am i wrong?

I think you are talking about soil buffer , but soil has his limits too , as i can see on your photos , your pots do not seems to be large , so if you give them alkaline water for too long , soil Ph will raise , and thus blocking some nutrients .

So forget about the soil buffer , mix your water and nutes , adjust Ph , and feed !

Your plants are about the right size, they look a bit light green all over, so a tiny bit more food or more regular smaller feedings would be useful.
The pot looks a bit small to me, but it is probably OK for an auto.

Allright, thanks for ur answer m8

Should i adjust with some natural ph down then because its an organic grow? What ive seen so should regular PH-down from GHE do more harm to the soilmix.

So. What about:
Citric Acid, is that allright to use for ph down?
If not, maybe I have to see if I can get my hands on «Canna Organic pH Down» ✌

The pots i use is about 2 Gallons (7,5L) each. That shouldnt do so much harm on the plant, right?

A.Kslo , organic nutes like biobizz and others , already has an acid tendency , so mixed with your water at Ph 7/7.3 , chance are after adding nutes it will be something below Ph 7 , maybe 6.8 , add a little acid , measure Ph , and go.

And for my case i use ph down from GHE too , and biobizz nutes , and bottled water , i can teel you that from going to Ph 7 with 1.5L bottled water, i only need 0.20 ml of Ph down to reach 6.5 , that's negligeable in terms of quantity , so you shouldn't be worried about this . if this is important for you, you can always try to find an organic Ph down .

Oh, okey. Im pretty happy with that answer. In short words, u say that i can stop looking for some organic pH down solution. I will just be fine with GHE Ph down, Biobizz Light mix soil and Canna Terra Veg ? :)

Thanks ✌
