Q.Soil problem??
I am an organic home gardener and was getting my garden boxes prepared for this season and I noticed that two of my boxes have very light brown almost orange soil in spots. What could that be? Deficiency? Disease? It isn’t through out the whole box, just in spots. It almost resembles saw dust. I am afraid to plant anything in that space until I know it’s safe. Thanks for help you can give me on this matter.

It is too difficult to say with just a description.
It could be something or nothing. I would suggest a soil test, and take a sample of the plant material in question to your County Extension Office.
