Get you plant development back on track with Dutchpro CalMag. Stunted growth and yellowed leaves are typical symptoms of Calcium and Magnesium deficiency, especially in soft water areas and RO systems.

It’s addition helps to keep your plant robust and fully functional. Dutchpro CalMag also contains an added hit of Nitrogen to reignite plant growth.
