Soil A 5 Liters Top Crop

two-part base fertilizer Soil A+B Top Crop

Soil A Top Crop is designed to work in synergy with its partner Soil B, forming the duo Soil A+B Top Crop that covers all the basic needs of cannabis cultivation in soil substrate.

Part A concentrates the essential elements that drive cell division, chlorophyll creation, and root architecture, promoting strong stems, healthy leaves, and an active metabolism. Thanks to its mineral formulation and solubility, it easily integrates into the irrigation solution and maintains pH stability when used following the correct mixing order (A first, then B).

In combination with Soil B, the resulting program allows you to adjust the EC and dosage for each phase of the cycle, avoiding deficiencies or excesses. It is a versatile base for growers seeking uniform results, ease of use, and compatibility with additives from the TOP CROP Fertilizers line.

Dosage and instructions for use Soil A+B Top Crop

• Mixing order: always add Soil A first to the irrigation water, mix well, and then add Soil B. Do not mix the concentrates directly with each other.
• Rooting / seedling: 1 ml of Soil A + 1 ml of Soil B per liter of water.
• Vegetative growth: 2 ml of Soil A + 2 ml of Soil B per liter of water.
• Transition to flowering: 2–3 ml of Soil A + 2–3 ml of Soil B per liter, depending on vigor and genetics.
• Frequency: 1–2 waterings per week, adapting to substrate moisture and plant response.
• Best practices: adjust pH, monitor EC, shake before use, and alternate with water irrigations if the substrate accumulates salts.

Composition Soil A+B Top Crop

Part A provides the base elements to support structural growth:

• Nitrogen (N): 3.5% – drives foliar growth and protein synthesis.
• Potassium (K): 3.5% – regulates stomatal opening and movement of water and sugars.
• Calcium (Ca): 2.8% – key for the cell wall and tissue integrity.
• Magnesium (Mg): 1% – core of the chlorophyll molecule; improves photosynthesis.
• Iron (Fe): 0.04% – essential cofactor in enzymatic processes and chlorophyll.

Used together with Soil B, the nutritional profile is completed to accompany the plant from the first weeks to flowering, maintaining a stable balance and predictable feeding in soil substrates.
