Mag-Pro

SUPERthrive Mag-Pro (2-15-4) is a premium nutritional supplement rich in phosphorus, magnesium, and sulfur. Originally developed by Dyna-Gro and now produced under the SUPERthrive brand, it's designed to be used alongside any complete nutrient formula as a blossom booster — the high phosphorus content promotes earlier and heavier flowering while the magnesium and sulfur enhance flower color, fragrance, and flavor development.

The 2-15-4 NPK ratio makes Mag-Pro highly phosphorus-dominant, providing a meaningful PK boost during the bloom phase without excessive nitrogen that could interfere with flowering. Magnesium supports continued chlorophyll production and photosynthesis throughout bloom, while sulfur contributes to terpene synthesis and amino acid production.

Use alongside your existing complete nutrient program during the flowering phase. Compatible with all growing media — soil, coco, and hydroponic systems. Can prevent and correct magnesium, phosphorus, and sulfur deficiencies while simultaneously stimulating bloom. Made by SUPERthrive, part of the Dyna-Gro family of plant nutrition products.
