Switched to 12/12 lighting this week. The plants look wonderful with no deficiencies or issues. Rooted Leaf nutrients are carbon based and 100%bioavailable, made from organic plants that are fermented. About 75% of the plants are land based and 25% ocean based. Things like Ginko Biloba, jasmine, ale, tea leaves, artichokes, juniper berries, licorice, oranges, lavender and ocean plants like kelp and sea algae. So far my plants really love these nutrients.
