supser soil for 12/12 from clone

im worried about buring them, should i make the soil mix weaker than the recipe calls for and add whats needed or not even bother mixing up super soil?i make my own castings and thermal compst,and obvi that wont burn, and i plan on mixing in kelp meal because micro nutes, and then add whats needed?

What did you decide with this? When I used supersoil I was into using a bagged soil such as Roots Organic to start then I would layer it at the bottom. But now I blend and also I am not doing a supersoil blend but rather I am focusing on composting. I used to use Black Gold to transplant into first which is a fairly inert organic soil but now I let my clones really get a nice set of roots then just transplant into Roots Organic solo cup and then finally I transplant that into a blended soil of my final mix. Which is still evolving.
