I can only tell you how I used to foliar-feed ... I mixed a 1/2 strength solution of my fertilizer, sprayed the undersides of the leaves, ONE day a week, then would spray the leaves with plain water the next day ... soil-watered the plants as needed, usually every 3-4 days ... be aware, if you foliar-fertilize indoors with organics, I hope you grew up on a farm :wtf:
