I'm still trying to improve baking myself so will offfer what little advice I can What are you baking in, are you using a cage?

cage is the reference to baking from high to low? if yes then yes i am, I have a low poly model  and a high the vertex are not touching and are fairly close to each other so i don't know what is causing it Ive played with them and they seem to have not much effect it almost feels as if its coming from my high poly but i do not have such geometry running across running across the mesh

A cage is a third mesh object that is an identical yet inflated version of your low poly model.  It's a visual representation of your ray cast distance and direction.  Typically when you get blank spots on your normal map like that it's due to your cage (whether automatically generated or manually provided) has not "inflated" far enough out to encapsulate the volume of the high poly model(s), or your arbitrarily-set ray cast distance is not high enough.

In Maya it's called an Envelope and if that's what you're using to bake maps, you should have an option to use and expand it in the Transfer Maps option window.
