there is something in my fertilizers.

I made 250 ml for my fertilizers to keep them for one month. After 20 days I see something inside like snow flakes. What is this? I also add the E300 and E202 but very few (almost nothing) as i saw the instructions on the label.

In my mixes, I add 1 mg of ascorbic acid (antioxidant) / ml of water and .4 mg of potassium sorbate (mold inhibitor) / ml of water.

Nope, it won't ruin it at all. It's a common addition to DIY liquid ferts.
