Dry Firt, Macro very cloudy?

Hey all, it’s been a while and wanted to know if this is expected. Setting up GLA Macro’s and I recall when mixed it should appear clear like clean water. Over the past few days however when I mix it things look cloudy with clear and yellow-ish partials on the bottom. Even after leaving on the self mixed for 12+ hours.

I have narrowed it down to the Potassium Sulfate powder being the cause. Before I buy a new batch wanted to ask if this just takes longer to mix or if the powder is bad.

I use RO/DI water and did have it hot in the beginning. In this picture I JUST have Potassium Sulfate (56G for 100ml). It’s been mixing for \~ 6hrs here
