Grow Mediums Do you need to dial down nutes when using PRO-MIX HP MYCORRHIZAE and worm castings?

[lunarman]

I can get some good EWC from a local worm farmer. And I want to switch from coco to HP Promix for a couple of plants. I will be adding some amendments like Bio Char, my own Mycorrhizae and worm castings.

I know worm castings can't burn a plant. But if you do add them would you reduce your nutes schedule? I also read that the NPK of worm castings can vary based on what the worms were fed. But I am just wondering if in principle would you reduce your nutes if you added castings to your mix?

In soil you will use less anyway, I use worm casting juice in my pot preparation. I understand it helps with a healthier soil and therefore healthier plants. I started with it and haven't stopped so nothing to compare it to, but my plants have taken a lot of abuse from me and survived.
