FloraFlex Cal + Mag + Iron Nutrients

Experiencing calcium, magnesium, or iron deficiencies in your high-performance growing setup?

The FloraFlex Cal + Mag + Iron supplement delivers targeted nutrition to correct common deficiencies and support vigorous plant development during rapid growth phases.

This specialized supplement integrates seamlessly with FloraFlex 2-part base nutrient formulas and any existing feeding program.

Formulated specifically for calcium, magnesium, and iron supplementation, this product addresses the unique nutritional challenges faced when using reverse osmosis water or growing in soilless media. The balanced formulation ensures plants receive essential secondary nutrients that may be lacking in sterile growing environments.

Essential for growers using RO water, coco coir, rockwool, and hydroponic systems where these critical nutrients are often deficient or unavailable. Plants experiencing rapid growth or developmental phases require enhanced levels of these elements for optimal cellular function and chlorophyll production.

The liquid formulation allows for both reservoir feeding and foliar application, providing flexibility in delivery methods to address deficiencies quickly and maintain consistent plant nutrition.

FloraFlex Cal + Mag + Iron FAQs

When should I use FloraFlex Cal + Mag + Iron? +

Use FloraFlex Cal + Mag + Iron when growing with RO water, coco coir, rockwool, or hydroponic systems. Also apply during rapid growth phases or when plants show signs of calcium, magnesium, or iron deficiencies.

Why do I need this supplement with reverse osmosis water? +

RO water removes essential minerals including calcium and magnesium that plants require. FloraFlex Cal + Mag + Iron restores these critical nutrients that are stripped out during the reverse osmosis process.

Can I use FloraFlex Cal + Mag + Iron with other nutrient brands? +

Yes, while FloraFlex Cal + Mag + Iron is designed to complement FloraFlex 2-part base nutrients, it's compatible with most nutrient programs when calcium, magnesium, or iron supplementation is needed.

What's the difference between reservoir and foliar feeding methods? +

Reservoir feeding (2-4 mL/gal) provides consistent, long-term nutrition through root uptake. Foliar feeding (15 mL/gal) delivers nutrients directly through leaves for rapid deficiency correction within 3-7 days.

How do I know if my plants need Cal + Mag + Iron? +

Look for interveinal chlorosis (yellowing between leaf veins), brown spots, or stunted growth. These symptoms are common with calcium, magnesium, and iron deficiencies, especially in coco coir and hydroponic systems.

Is FloraFlex Cal + Mag + Iron safe for soil growing? +

Yes, FloraFlex Cal + Mag + Iron is compatible with soil applications, though it's primarily recommended for hydroponic use. Soil growers using RO water or experiencing deficiencies can benefit from supplementation.

When should I adjust pH after using this supplement? +

Always adjust pH to proper levels after mixing FloraFlex Cal + Mag + Iron with all other fertilizers and additives. The supplement may affect solution pH, so final adjustment ensures optimal nutrient uptake.

How quickly will I see results from this supplement? +

With foliar application, expect improvement within 3-7 days. Reservoir feeding provides gradual improvement over 1-2 weeks. New growth should show healthier coloration and reduced deficiency symptoms.
