For Bountiful Flowers & Fruits, Use the Custom Nutrient System Tips Below

Shake well before using. Whether mixing liquid nutrient concentrates, or diluted fertilizer solutions, always mix well before application.

Reduce nutrient strength in very bright, hot or dry conditions, or if plants show stress.

Add CNSMicro to fresh water and mix well before adding CNSGrow or CNSBloom. Never combine undiluted CNSMicro with other products as doing so may cause nutrient lockout.

Always monitor water quality and control overall nutrient strength.

Replace blends every 1-2 weeks to maintain proper nutrient ratios and prevent imbalance.

For best results, maintain nutrient pH between 5.5-6.5. Adjust as required depending on season, growing region, or environment.

CNS formulas are concentrated to the limit of solubility. Protect from freezing and store out of direct sunlight. If crystallization occurs, remix the entire contents of the bottle with an equal amount of hot water; and double the amount used in your application formulas.

Use as part of a complete fertilizer program.
