Are these pests on my Hinoki cypress?

First time I’ve noticed these little white “x’s” on the bottoms of all my hinoki cypress needles. Is it some kind of scale or other bug?

Also getting some brown tips…

The white criss-cross pattern is normal, and the foliage looks really healthy! Am not sure what’s going on with the branch that’s browning out, but I wouldn’t worry about it unless it continues down the branch. If that happens I’d guess there is an issue with the roots, but overall the tree looks good.

Is the branch with dieback wired? Sometimes hinoki just … does that for no reason, sometimes it can be the result of wire cutting in I’ve noticed

The branch was wired through the winter. I took off the wire during the Spring growth period. I am in the process of putting it back on now that Summer has kicked in.
