What do you use for foliar spray?

I have been using a 1/4 strength mix of floragro and floramicro as a foliar spray for my plants. I recently bought a gallon of liquid karma and I'm thinking about adding it to my foliar spray and I was wondering if anyone had any experience adding liquid karma to theirs?

Also, I wanted to get an idea of what everyone else uses as a foliar spray.

i dont generally use a foliar spray. if they are getting all they can handle through the roots why spray the leaves.
but i have used foxfarms big bloom at 1/4 strength or less.
