Naked100 Sour Sweet WUT R U DOING?

Naked100 usually does a great job of using minimal (or no) artificial sweeteners in their liquids. However, the new Sour Sweet liquid instantly gunks up my tank. Perhaps it's better dripped or vaped at lower wattage (<48.0), but the liquid turns brown within several hours of filling my tank, I can't get a consistent flavor and have ruined two coils now trying to remedy this. Other than throwing away trash, does anyone have tips for liquids like this?
