So Confused On Soil Ph...please Help

[HumbleNewbie]

Hey everyone,
I’ve read numerous posts on this forum and am more confused than ever. My plant seems to have a magnesium deficiency week one into flower. I am in 7 gal geo pot with subs super in bottom 40% topped with mix of coast of Maine stonington and happy frog blend. I run water through small boy to dechlorinate. I added 2 tsp roots bloom terp tea to base so far. I also did a watering using slf-100 to see if it helped. Only other additives I’ve added to water are mammoth p every other watering and suite leaf cal mag. Today I ph’d my water to 6.5 before watering and tested runoff. It came out at 7.1. Any suggestions are appreciated.

Ph after adding nutrients?

It was 6.5 after I added cal mag

It was 6.5 after I added cal mag

Runoff increased .6

Test ph after all nutes have been mixed.

I’m thinking coffee grounds on surface of soil to water through but not sure how much.

Test ph after all nutes have been mixed.

In water? If so I’m not really adding much nutes.

Dude runoff is not accurate do a slurry test if you want to know for sure.

What nutrients are you feeding your plant besides cal mag?

Tips on slurry test? H20 to soil ratio?

I’m running Subcool super soil mix in lower half of pot. Nutes are mixed into soil. Ewc, guano, etc

If you need to lower the soil pH, you can add a variety of organic material to lower it. Sulfur will also lower soil pH.
