Pathogen or Pest

Hello,

Was wondering if this is something of concern? I cannot identify any pests with scope and typically spray lost coast plant therapy as preventative measures. Plants are happy otherwise. Just was wondering if someone had laser vision with some type of identification. Must be something ay?

Think you have thrips. Pic 3 top of leaf in the margin. They are hard to see. I use spinosad for pest. Cheers.
