API Pro Series Leaf Zone 16 ounce


Add to Cart:

API Pro Series Leaf Zone is the perfect companion to Flourish Comprehensive as it contains chelated iron and potassium. Formulated for plant leaves to easily take in these much needed compounds.

When deficient in iron plant leaves will begin to turn yellow while the veins remain green; and when deficient in potassium plant leaves will develop tiny pinholes that will grow in time. Using API Pro Series Leaf Zone will ensure your plants have the necessary iron and potassium to avoid these common deficiencies.

16 ounce bottle treats 946 gallons.
