Plant-Prod MJ™ Spike (CaMg) has been specifically formulated to meet the high demands of cannabis plants throughout the entire production cycle. This fully chelated formulation provides ample amounts of calcium and magnesium in a desirable 2:1 ratio.


The absence of nitrogen, phosphorus and potassium allows the use of this formulation at any stage of production without the risk of encouraging vegetative growth when undesired. Ideal for use with reverse osmosis (RO) or city water when calcium and magnesium levels are usually low.


  • Supplement in addition to appropriate feed throughout production cycle
  • Requirement and rate to be determined following water analysis

Available in 6oz powder.
