Just sprinkle it on top of the soil - or better yet - sprinkle it on top of your mulch.
The Epsoma stuff is organic. No worries about salt built up in an organic grow. Some of us have been running containers without drainage holes for a long time without any issues.
Good reason to make the switch. I've been using the same soil mix in the same container continuously for over a year.
I can be really easy. This is how I do it:
(1) Chop the old plants at the base - leaving a stump and a roots.
(2) Cut-dig holes for the new plants.
(3) Plant new plants in the holes and water.
(4) Observe over the next week. If they look needy top dress some guano and castings and apply a ACT.
I also return all plant material back to the soil. Stems and fan leafs get used as mulch immediately after harvest. The sugar leafs and popcorn buds will get used for mulch after bubble hash extraction. Check out the recycling thread in my signature for more information.

Dude, you've been an incredibly wealth of information for me. Thank you so much.
Any chance I could see a pic of your soil bed with all the mulch on it. I'm having troubles imagining what that might look like. Do you chop up all the stalks and such?
Edit. Nevermind, I see that your signature has lots of info!
