Topic: How do I mix your nutrients?

There are no “hard” rules when it comes to mixing our nutrients; however, there are some tips
that might be helpful. For example, it’s typically recommended to add the least soluble, or heaviest
nutrient to your reservoir first. For instance, Micro is the “heaviest” fertilizer in our GP3 nutrient
system and by adding it to your reservoir first, Micro will be given more time to become soluble in
water. Also, some fertilizers will either raise or lower the pH of your nutrient solution. PK Spike and
Plant Guard are two examples of products that will raise the pH of your nutrient solution. So, to
avoid complex measuring, mixing and buffering, it’s highly recommended that fertilizers with a high
pH are added last. For general mixing and measuring information, refer to our online nutrient
calculator.
