Tomato Fertilizer 4-18-38 Hydroponics, Soil & Foliar Application

Tomato Fertilizer 4-18-38

Maximize your harvest with Tomato Fertilizer 4-18-38, a premium, 100% water-soluble nutrient blend specifically formulated for the flowering-through-harvest window of fruiting nightshade crops. With a low-nitrogen, high-phosphate, and extremely high-potassium ratio, this formula directs your plants' energy strictly toward robust fruit development rather than excessive leafy growth.

Ideal For:

• Fruiting Nightshades: Highly effective for tomatoes, peppers, eggplants, and tomatillos.

• Versatile Application: Dissolves completely and cleanly for use in soil, containers, drip fertigation, hydroponics, and foliar spraying.

Key Features & Benefits:

• Targeted NPK Ratio: * 38% Potassium: Maximizes fruit sizing, sugar transport, firmness, and post-harvest shelf life.

  • 18% Phosphate: Drives prolific flowering and reliable fruit set.

  • 4% Nitrogen: A controlled dose to keep energy focused on fruit production.

• Chelated Micronutrients: Fortified with EDTA-chelated iron, manganese, zinc, and copper, plus essential boron and molybdenum in every bag.

• Tested & Certified: CDFA registered and rigorously third-party lab-tested for heavy metals, with results consistently well below required limits.

Important Handling & Application Rules:

• Calcium-Free by Design: This formula intentionally omits calcium, as calcium and concentrated phosphate will form an insoluble precipitate when mixed in a stock solution. Always apply a separate calcium source independently for a complete nutrient program.

• Mixing Best Practices: Pre-dissolve each fertilizer separately and always verify your solution's pH and EC before applying.

• Foliar Spraying: To prevent leaf burn, only apply foliar sprays in the early morning or late afternoon when temperatures are below 85°F.

• Storage: Always store tightly sealed in a dry environment.
