Correct pH for coco/worm casting mix?

Hi fellas,

What's the best pH for coco, if amended with 20% EWC? Is it still considered a soiless mix?

In my experience with coco, 5.9 - 6.3 is the butter zone.

I saw on Joe's Fresh Guide that the proper pH for any medium with 20% or more field soil is 6.2-6.5. Any opinion?

Any idea?

Why coco? Yucch!
Peat, EWC and perlite.....a soil "base".....
You are correct on the pH......ewc in coco is now not a hydro run...
