DIY Fertilizers

started from a concern of nutrient deficiencies in my aquarium.

i have heard seaweed is a great way to provide a complete mix of nutrients for our planted tanks.
-i assume cleaned and dried so it doesn't affect tank chemistry
-using the seaweed to make a tea from & using that.

otherwise looking up DIY hydroponic fertilizers... and i'm stuck.
10 ounces sodium nitrate (NaNO3)
10 ounces calcium nitrate (Ca(NO3)2)
10 ounces potassium sulphate (K2SO4)
15 ounces superphosphate
5 ounces magnesium sulphate (MgSO4)
1 ounce iron sulphate (FeSO4)
1 teaspoon manganese sulphate (MnSO4)
1 teaspoon boric acid powder (H3BO3)
teaspoon zinc sulphate (ZnSO4)
teaspoon copper sulphate (Cu2SO4)

---

has these:
-Nitrogen (N)
-Phosphate (PO4)
-Potassium (K)
-Calcium (Ca)
-Magnesium (Mg)
-Sulfur (S)
-Boron (B)
-Copper (Cu)
-Iron (Fe)
-Manganese (Mn)
-Zinc (Zn)
-Sodium (Na)

seems to be missing these:
-molybdenum
-cobolt
-nickel
-chlorine
-silicon
they're close enough to trace levels, but missing regardless :(

i like the idea behind using other plant material (such as seaweed mentioned)

aside from that, what else (other mixes) can be used to provide a complete mix of plant nutrient requirements ? or is that where everything is going to end?, using one plant to provide all needed nutrients for our planted tanks.
