Yes, all fertilizers will impact the pH of your nutrient solution. Most of our products like Massive
and Medi-One are acidic, and will therefore lower the pH of your nutrient solution. Others, such as
PK Spike and Plant Guard are alkaline and will raise the pH of water. Most plants will uptake
nutrients at pH levels between 5.8 – 6.5. So, measure your inputs and make sure your nutrient
solution is between these levels.
