Can foliar fertilizer be used in my FF/OF soil, or is it strictly only used topically on leaves? Does this type fertilizer have any use for growing cannabis?
I don’t care for it myself. I like to keep the leaves as dry as possible unless I have to spray with some captain jacks dead bug for pest control. I only use nutrients that are absorbed through the roots.

The only reason a plant should be sprayed with anything is to treat bugs or mold.
