Strange White Top on this Bud

I have a Flo Stain which is 8 weeks into flowering. amp;nbsp;One of the buds has a white top. amp;nbsp;It looks like the leaves are white along with many pistals too. amp;nbsp;The Flo buds all have plenty of white pistals ,but this one has what looks like white leaves. amp;nbsp;Anyone have any idea what this is ? amp;nbsp;
