Although equilibrium does have nutrients plants need (mainly Calcium, Magnesium, Potassium, sulfur and manganese, that is only 6 of the 14 plants need. Equilibrium is mainly sold as a remineralizes or GH booster. GH boosters are necessary if you have soft water. You likely have soft water given your location is listed a Vancouver. Get a GH kit and after each weekly water change adjust the GH to 2 degrees above the tap water GH level. For this you probably should buy a GH test kit. I would then get a good fertilizer like Thrive (nilocg.com, amazon.com or other places). For root tabs I would recommend Sachem root tabs. These three should cover most of the nutrients plants need.
The 14 nutrients plant need are:
nitrogen(N), phosphorus(P), potassium(K), CalciumCa), Magnesium(Mg), Sulfur(S). These are collectively call macros (Plants need a lot of these.
Micro nutrients are: Chlorine(cl), Iron(Fe), Boron(B), ManganeseMn), zinc(Zn), copper(Cu), molybdenum (Mo), nickel (Ni). Plants need less of these.
Most fertilizers don't have Calcium. Other fertilizers don't have sulfur. Which is a good reason to use the Equilibrium. If any of the above nutrients are missing your plants may not grow or grow very slowly. Slow plant growth typically Encourages algae growth. While rapid plant growth tends to suppress Algae growth.
