I just mixed up my first batch of liquid fertilizer. The problem that I am having is that the dry ferts arent readily dissolving in the water. Is this normal? I used the petalphile calculator to get the necessary grams.

What fertilizer and how much of it are you trying to dissolve?

Are you trying to mix them together?

How long did you agitate for? It can take some time to dissolve some chemicals.

I waited 2 days and it wouldn't dissolve. I ended up boiling the water first and then adding it to the solution. It dissolved immediatley and looks great. I also added excel to both the macro and micro mixture to help avoid any mold or fungus.

If you don't try to make such a concentrated solution, you won't have problems dissolving the chemicals. I don't see any advantage to using higher concentrations than what dissolves easily and quickly. I use tap water, which is pretty soft, and add about 1 tsp of KNO3 to 16 ounces of water, plus smaller quantities of the other chemicals. Never a problem.
