Nutrients Can anyone help with explaining how I get the pH of my soil and feed correct?

Hi all,

I posted here about an issue I had with my plants in my last run.

It was narrowed down to a pH issue or the extreamley high concentration of CaCO3 (very hard water in other words)

I decided to fit a reverse osmosis for he next grow to eliminate that hardness of my water.

I also want to get my pH right. My water, after nutes and cal-mag is around 6pH.

The soil was on average 5.8 (checked with soil pH probe).

I therefore assumed that:

Desired pH for soil and feed is 6.2

Difference in Water pH and desired pH = -0.2

Difference in soil pH and desired pH = -0.4

So the total difference is -0.6 pH.

I added pH to my feed untill it was 6.6pH (which is an increase of 0.6; the difference between my desired pH and the soil + feed pH.)

However, after watering with my feed at 6.6pH, the soil is still to low, sitting in the 5.6-5.8 region.

How can I get my soil at the correct pH?

Cheers

It’s probably going to take some time for the soil pH to raise, which is kind of a good thing, since changing it slowly can help avoid over correcting and ending up doing what basically amounts to chasing your tail with bottles of pH up and down.

To be able to help ya out more it would help to have the following info:

• The soil you’re using
• Pot size
• Which nutes are you using?

If you’re growing organically, ph isn’t as big of a deal since the microbes, fungi, etc are feeding the plants when they need it, instead of the plant having to soak up what’s available.
