Lettuce & Leafy Greens

Nitrogen-forward nutrition for lettuce, kale, spinach, chard, and every leafy crop where the harvest is the foliage itself. Leafy greens want steady available nitrogen, adequate calcium to prevent tip burn, and magnesium for deep leaf color — without the heavy phosphorus and potassium that fruiting formulas carry. This collection centers on Lettuce Fertilizer 8-15-36 for hydroponic and soil programs, backed by Calcium Nitrate and Cal-Mag Plus for tip burn prevention, and fast organic nitrogen sources like Blood Meal and Feather Meal for garden beds. All products are CDFA registered, third-party tested for heavy metals, and made in our FDA-registered California facility. For hydroponic lettuce, add calcium to the reservoir before phosphate sources — the same rule that keeps every recirculating system clean.
