LSN ‘proprietary’ blend of our favorite organic fertilizers with added minerals including iron, calcium, and magnesium. Great for spinach, peppers, tomatoes, and any veggie in the fruiting stage of its cycle. We use this on all of our flowering plants, as well as any of our fruiting trees. A great all around OMRI organic fertilizer. We hand mix this fert., which will come with recommended usage. We offer this up as a benefit to our customers, and it may not be for customers who need a more structured NPK formula. This stuff absolutely is golden and we will likely not sell it here online forever. Get it while it’s here…or not.
