Magnesium Boost
Soluble magnesium supplement — Soluble Mg²⁺, Foliar-active.
N–P–K4-0-0
Soluble magnesium supplement from Vegalab Crop Science, powered by Magnesium sulfate · urea · nitric acid. Magnesium Boost targets Magnesium deficiency, chlorophyll synthesis, photosynthesis, and has been tested on Grapes, Tomatoes, Citrus and Cucurbits.

Mode of action
Soluble magnesium reaches chloroplasts via foliar absorption and corrects chlorophyll-deficiency chlorosis. Photosynthetic capacity restores within days; interveinal yellowing reverses.
