there's an article from skunk magazine titled stunning cannabis flowers: chitin, sulfur, and silicone
I know bananas have sulfur and I think even unsulfured molasses might contain some naturally and not from treating the sugar cane
Absolutely! Sulfur is critical! Resin/terpene production. I use langbeinite for Sulfur/Mag/K.
I add a silicon source. Cattails in the worm bin or compost pile will bring silicon. There is a mineral/mined product i use as well.
My worm bins get Dungeness crab and shrimp shells. The soil mix gets crab/lobster meal. They bring the chitin.
Manganese is often overlooked. So is boron.
Azomite adds most of the stuff like manganese and boron. Fe - Iron is also critical to a point.
