Plant-Prod® Chelated Iron 11% DTPA 5lb

DTPA-Chelated Iron Supplement for Correcting Chlorosis, 5lb

Iron chlorosis shows up as yellowing between leaf veins and is one of the more common micronutrient deficiencies growers run into, especially in higher-pH soil, soilless mixes, or nutrient solutions where iron becomes less available to plant roots. Plant-Prod Chelated Iron 11% DTPA uses a DTPA chelate to keep iron soluble and available across a wider pH range than an unchelated iron source, correcting chlorosis without waiting on a pH adjustment first.

This 5lb package is a professional-grade concentrate suited to hydroponic, soil, and soilless growing environments rather than a small retail-size correction product.

Key Features & Benefits

• 11% chelated iron — a concentrated iron source rather than a diluted retail blend.
• DTPA chelation — keeps iron stable and available across a wide soil and nutrient-solution pH range.
• Corrects iron chlorosis — addresses the interveinal yellowing typical of an iron deficiency.
• Works across hydroponic, soil, and soilless systems — one product for multiple growing methods.

Who Should Use This

This fits growers seeing interveinal yellowing consistent with iron chlorosis across hydroponic, soil, or soilless systems, particularly in higher-pH growing conditions where an unchelated iron source becomes less available to roots.

Frequently Asked Questions

What does DTPA chelation actually do

DTPA binds the iron in a molecular structure that keeps it soluble and available to plant roots across a wider soil and nutrient-solution pH range than an unchelated iron source would allow. That's what lets this product correct chlorosis reliably even in higher-pH growing conditions where plain iron sulfate or similar sources become locked out.

How do I know if my plants have iron chlorosis

Iron chlorosis typically shows up as yellowing between the leaf veins while the veins themselves stay green, usually starting on newer growth first. That interveinal pattern is the main way to distinguish an iron deficiency from other nutrient issues.

Can this be used in hydroponic systems as well as soil

Yes, it's formulated to work across hydroponic, soil, and soilless growing environments rather than being limited to one growing method. That flexibility makes it useful for operations running more than one production system.

Is this a standalone fertilizer or a supplement to a base nutrient program

It's a micronutrient supplement meant to correct a specific iron deficiency, not a complete base fertilizer on its own. Use it alongside your regular feeding program when chlorosis symptoms appear rather than as a replacement for balanced nutrition.
