Hydroponic Fertilizer 5-0-1 Base Nutrient with Calcium and Chelated Iron for Soil and Coco Growing
This hydroponic fertilizer supplies calcium, chelated iron and trace minerals as the foundational nutrient in the Cronk Classic 3-Part system. Its 5-0-1 formulation supports plant nutrition in hydroponic setups, soil and coco coir, helping plants use nutrients supplied by the other fertilizers in the system.
EDTA-chelated iron stays available in hydroponic reservoirs, while calcium supports cell walls and nutrient transport. The micronutrients remain plant-available across pH 4.0–6.5, and the same three-part system can be used from seedling through harvest.

Frequently Asked Questions
Can this 5-0-1 fertilizer be used in soil and coco coir?
Yes. This 5-0-1 base nutrient is intended for soil, coco coir and hydroponic setups as part of the Classic 3-Part system.
Is this the entire three-part feeding system?
No. This fertilizer is the foundational micronutrient component of the Cronk Classic 3-Part system, used alongside the other fertilizers in that system.
What makes the iron suitable for hydroponic reservoirs?
The iron in this base nutrient is EDTA-chelated, which helps prevent precipitation and keeps it available in hydroponic reservoirs. The supplied micronutrients remain plant-available across pH 4.0–6.5.
When can this base nutrient be used during growth?
This base nutrient can be used from seedling through harvest within the same three-part system.
