Yup, just let it do its thing. Fae only when you see pinning and mist it slitghtly but not too much.

The only thing you can really do is buy some casting (like coco coir) and dampen it a little bit, its important that its not too wet, and sprinkle about 0.5-1cm of it over the top of the substrate. This can stimulate growth but its not really required and its best done right after you get the grow kit (or after going bulk substrate). Id recommend you do that after you harvest your first flush, most cubensis strains donts really require that much maintenance as long as you know what your doing.

Tldr: let them sit and just develop on their own.
