Jack's Nutrients 5-12-26 Part A - 1 kg

Jack's Nutrients 5-12-26 Part A is a Jack’s Nutrients Part A formula for general vegetative growing, designed as a base nutrient component to support vigorous plant growth. It’s built to provide a focused vegetative nutrient balance that fits a wide range of growing styles without turning into a single-crop specialty product.

This redesigned blend is described as an improvement on the classic “Part A” formula, with purely soluble and available nutrients intended to give the grower maximum flexibility. That flexibility matters when conditions shift from one space to another or when you’re managing different crop types and still want a consistent vegetative foundation. The goal is straightforward: keep nutrition efficient and dependable during vegetative growing, so plants can maintain strong momentum as they build green mass.

The nutrient profile is 5-12-26, presented as a specific balance of macro, secondary and micronutrients that delivers an efficient combination of nutrients. Instead of leaning on extra add-ons or niche “booster” positioning, this Part A formula focuses on an all-around vegetative balance that supports vigorous plant growth from day to day. It’s a clean approach for growers who want a reliable baseline with a clear nutrient ratio and a formulation designed around soluble availability.

Because Jack's Nutrients 5-12-26 Part A is positioned as suitable for many different growing environments and crop types, it’s a practical fit when you want one vegetative formula that can stay consistent across a variety of setups. This product is a good fit for growers looking for an improved Part A formula for general vegetative growing, with soluble, available nutrients and a balanced macro, secondary and micronutrient design that supports vigorous plant growth.
