Hello,

As per the title. I discovered my soils ph was high.

Here is the criteria

7 gal fabrics
Kis organics, bio char living soil
Week 7 from sprout, showing cal mag deficiency but its actually a ph issue.

Did slurry tests.

Used distilled water with a base of 2ppm and around 7.0ph

1 part soil to 2 parts water. Stirred vigorously every few minutes for about an hour.

I tested it unfiltered. Then again after filtering the water from the dirt via paper towel .

Unfiltered was a ppm of 627 with a ph of 7.7

Filtered was a ppm of 807 with a ph of 7.5
Presumably the paper towel cause the ppm to spike.

Anyways . Can I just use tap water that's been PHed dowm to like 6.5 and flush? Or should I dechlorinate it?

Thank you!

You can but make sure to dechlorinate. I have used ground coffee beans with great success. They naturally have a pH of 5 +/- some. No flushing required.

Could I just skip flushing them and just water with a lower ph for a few watering?

Like drop to 6.0 with the water?

Really to change your soil long term you need to make a change to it. Simply changing the water going into the medium doesn't change the medium, it only temporarily changes the pH. In my experience something needs to be added like elemental sulfur, pine needle mulch, coffee grounds, ect.
