Be careful using old bottled nutrients, or you might experience this...

I used an old bottle of a flowering nutrient, and the next morning some of the leaves were discolored and disfigured.

I'm sure this is what is called a nutrient burn, correct?

I thought nute burn happens along the edges

Cant see any nute burn here.

Unless your using organic nutrients then I don't think your problem is the bottle of nutrients.
