I mix down to earth 3-3-3 with perlite vermiculite and worm castings into my soil and let cook for about 3 weeks
You need 1 1/2 cubic foot of preferred soil to start with
I use recharge also when the soil is first mixed and few times when top dressing with worm castings.
I put dynomyco in the hole when put plant in
Need to water from top around the plant for about week before filling up with water
I get my water close to 6.0-6.3
I too dress with build-a-flower and worm castings about 2 weeks before flip
