Bush Doctor Manganese

Bush Doctor Manganese by FoxFarm is an organic liquid micronutrient supplement providing 5% manganese, formulated to correct manganese deficiency — a micronutrient that plays a key role in photosynthesis, enzyme activation, and helping plants resist environmental stresses.

Manganese deficiency in cannabis typically shows as interveinal chlorosis on young leaves and is often triggered by high soil pH (above 6.5) or cold growing temperatures rather than a true lack of manganese in the growing medium. When deficiency is confirmed, Liquid Manganese provides a bioavailable supplemental source that restores photosynthetic efficiency and overall plant vigor.

With a 1-0-0 NPK ratio and OMRI Listed certification, it fits into organic growing programs without introducing synthetic chelates. Apply as a root drench or foliar spray when symptoms appear. Not a routine supplement for most growers, but a useful tool when pH fluctuations or environmental stress cause manganese lockout. Best stored separately from other nutrients to avoid cross-contamination.
