# 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.
