Greenway Biotech, Inc. Manganese Sulfate is one of the most potent fertilizers on the market,  over 99% pure and is a powder, it is perfect for palm plants and hydroponic applications

Manganese deficiency or "frizzle top" is a common problem in palms. Symptoms first begin to show on the newly emerging fronds (leaves). The fronds will appear chlorotic (yellow), small, and weak looking. As the deficiency progresses, fronds will emerge withered or scorched in appearance, dwarfed, and distorted. This is what gives "frizzle top" its name. If not corrected, the palm will stop growing and only small brown stubs will emerge, this is quickly followed by the death of the palm. All palms can benefit from regular applications of Manganese Sulfate. Some of the most susceptible palms to manganese deficiency are Queen Palms, Royal Palms, Pygmy Date Palms, Paurotic (Everglade Palms), and Coconut Palms.
