Strange Foliage Discoloration on my 'Honeycrisp' Apple Tree

Well. Walked my slope a couple of days ago, and found my brand new this season 'Honeycrisp' apple tree displaying this:

(a little out of focus, sorry)

At first I thought this might be a virus of some sort, but in checking around, I think it might be streptomycin injury, based on what I'm seeing here on WVU Extension's site:

Opinions? I have not sprayed with Streptomycin, so that would mean to me, that either DWN or from Bay Laurel Nursery.

Google "Honeycrip Yellows". That's my guess.

Thanks, olpea, you are correct. Here's a link showing the identical strange mottling that my Honeycrisp is exhibiting. So glad this is nothing to worry about. I'm eyeballing a couple of my pears for Fireblight right now. I think I may prune just to be safe. Sometimes here in our area, very mild infections will manifest in what looks like burnt edges on the leaves. So, two of my pears are showing this - time for the pruners.

My honeycrisp often gets strange coloration on the leaves, too, but it never seems to hurt the tree any.
