DIY fertilizer not dissolving

bat_billy · 12-07-2012, 11:16 PM

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.

Use distilled water for best results. If you have hard tap water, your ferts aren't going to dissolve easily.

Also try heating your water, it makes dissolving a lot easier.

Im going to try to heat the water to help them dissolve. Im using RO water so ot should be plenty soft.

On some of mine, they have to sit overnight. By the next morning, after a good shake, everything is dissolved.

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.

Same issue here for the Macro liquid mix. I used RO water.
Should I just transfer this to a pan and heat it?

It has 29 grams of K2SO4, 33 grams of KNO3, 3 grams of KH2PO4 and 20 grams of MgSO4

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.

Can I move this to 1 litre bottle (to dissolve it) and double my dosage?
