Grotek - Blossom Blaster Pro Liquid - 1-4-0 – 1 Liter

Grotek Blossom Blaster Pro Liquid (1-4-0): High-Phosphorus Bloom Fertilizer for Hydroponics Grotek Blossom Blaster Pro Liquid (1-4-0) is a concentrated phosphorus-forward bloom fertilizer formulated to support flowering-stage nutrition in recirculating and drain-to-waste hydroponic systems. The 1-4-0 profile delivers targeted phosphorus support while keeping nitrogen modest, allowing growers to layer it into existing base nutrient programs without creating NPK imbalances during bloom. E.C.-Compatible Liquid Bloom Fertilizer for Reservoir and Run-to-Waste Feeding Designed for E.C.-managed feeding programs, Blossom Blaster Pro Liquid integrates cleanly into measured hydroponic schedules across reservoir and run-to-waste setups. Apply alongside a balanced base nutrient from early flower through mid-bloom, adjusting dosage based on crop response and target EC/PPM range. Available in 1 L, 4 L, and 23 L to scale from single-tent operations to larger commercial grows. Key Features High-Phosphorus 1-4-0 Formula: delivers elevated phosphorus support during the bloom phase without excess nitrogen that can disrupt flowering performance E.C.-Compatible Liquid Format: fits cleanly into measured hydroponic feeding programs and reservoir-based schedules in recirculating and drain-to-waste systems Low-Nitrogen Profile: the modest 1% nitrogen level helps maintain appropriate NPK balance during flowering when reduced nitrogen input is beneficial Metabolic Energy Support: phosphorus-dense formula supports cellular energy transfer and key metabolic processes during peak bloom-phase demand Three Size Options: available in 1 L, 4 L, and 23 L to scale from single-tent grows to larger commercial hydroponic operations
