Just fed and watered yesterday looks like its dry and the ph is on the high side
I started feeding last week as opposed to water only

Those three way meters are worthless. Digital ph meter will give you a better indication of what’s going on.


hows this?

Luster Leaf 1835 Rapitest Dig 3W Analysis, 3-Way Digital Soil Analyzer


Gain Express Soil Ph & Moisture Meter 295mm Long Electrode

Or what would you recomend?

More like this:
PH Meter, PH Meter 0.01 PH High Accuracy Water Quality Tester with 0-14 PH Measurement Range, PH Meter for Water/Brewing/Food/Soil/Sauce/Laboratory, TDS Meter, PH Pen

Thanks but isn’t that a ph water tester?

How does it test soil?

Yes it tests water and nutrients solution. Your soil acts as a buffer when you add your adjusted nutrient solution. Your nutrient/water solution goes through the soil, picks up the pH of the soil, and you check the run off.
When doing this, and you start out at 6.5 and comes out of the bottom of the soil is 6.0. That means your soil is between 6.5 and 6.0.
Slurry test
To check your actual soil pH take some soil from desired area (root zone is best) mix with water just enough to to make a pudding consistency.
Then insert your ph meter after 15 mins, and wait for it to adjust.

This is how you should be checking your ph.


Good advise thanks
