Dutchpro Leaf Green is used to achieve good leaf development in plants, giving them a healthy, vital look. It is especially recommended for plants that have noticeable difficulties with their development. Leaf Green also gives plants with a yellowish tinge a fresh green color. It’s also great at improving nutrient uptake. Leaf Green is non-ammonia-based and comes ready to use as a spray-on liquid. Apply at least three hours before the lights go on. Dutchpro nutrients are stable, clear, and contain organic elements. They are available in a variety of sizes.
