there should be some here someplace. Kelp, guano earth worm castings (EWC) or compost teas make great foliar feed. Lots of recipes. Basically, put the nutrients in a sock (or pour freely) into a tote of water. I add a biotic formula of plant food for additional bacteria and a quarter to half cup of unsulphered mioolasses , 75-80º with air bubblers for two days. Strain, dilute 4:1 with water and spray.
