White streaks inside my Amazakoe

I've never purchased this wood before, saw it at Woodcraft and got some. When I milled it it had white blotches and streaks inside of the wood. I can see it on the endgrain where I cut. I tried looking it up but found nothing on this wood species or in general. Looks like drywall smear in the woodgrain. Is it something I need to be worried about? Thanks.
