@JoetheChro will have more knowledge on this than I, and especially because if I’m not mistaken your “soil” is actually a “soilless” mix which I have not used.It is canna professional and sometimes i use canna professional plus (canna professional is 1ec and pro plus is 1.2ec )

They just say use cannazym if you going to re use our soil. Thats it.
