What Should My Runoff pH Be in Soil

Typically, you’ll see 6.2 for soil, and 5.8 for hydro. In an ideal world, your first few feedings will be within 1 pH measure of that target, and after a few weeks will converge on that number. If this happens, good.

Why is my runoff pH so high?

High runoff pH usually comes from two things- substrate buffers and nutrient absorption. … The strength of these substrate buffers, as long as they are not amended, will weaken over time. Quick absorption of Nitrogen can also cause the pH of your substrate to rise.

How do you measure pH runoff?

1) 30 minutes after your normal feeding take 1-2 liters of 0.0 EC water and pour it over your plants medium at random spots and catch the runoff with a clean dish. 2) Measure the results in a clean shot glass. Take at least a 1 min reading of the pH and EC. This is your actual EC/pH.
