Plant Marvel 20-7-20 + Alkaline No Boron 25lb — Single Unit

High Magnesium NO BORON. This formula supplies over half of its nitrogen in the nitrate form and is an ideal feed for crops responsive to nitrate nitrogen during low light periods. An ideal formulation for growers with a high sodium level in their water. The interjection of a antagonistic ion like magnesium decreases the negative effects caused by sodium. Also an excellent feed for poinsettias because of increased magnesium and moderate potential acidity.
