How to validate array of array inputs Jquery?

How do we validate array of array input boxes using jquery validation plugin?

Is it incorrect to add the same JQuery Validate rule twice to a dynamic field and is it detrimental?

I have a large number of dynamic cloned fields on a form. The fields are cloned groups.
