This leaf is off of my Utah Giant tree. Not all leaves are affected but many are.

I have no special knowledge, but a Google search suggests maybe Magnesium deficiency, or herbicide/pesticide damage.  

Do you have poor drainage, potential exposure to herbicides, or soil nutrient deficiencies?

Thanks Jafar. Magnesium deficiency makes more sense than herbicide damage.

I had a soil analysis done before planting the orchard last spring and it showed a very low pH with a recommendation to add 200 lbs of limestone per 1000 square feet. I did not actually get around to putting down the limestone until this spring although I did excavate each hole at planting time and replace the dirt with purchased topsoil that was pH 6.5 as well as spread several handfuls of limestone around the holes. I may have not excavated enough of the hole for that particular tree.

What was the surrounding soil like?  Is it possible that you've created a basin that isn't draining, and drown the roots?  How long ago did you plant it?  Has it grown?

Is it getting some nitrogen?

Can you share a picture of the whole tree and its surrounds?

The beds are well drained being in gravelly loam at significant elevation above nearby brooks. The trees in this orchard were planted out in spring 2020 but they were all fairly large when they arrived. Utah Giant came from Peaceful Valley Farm Supply/groworganic.com and is on Newroot-1. It is growing pretty well as are all the cherry trees as you can see below. I side-dressed the trees in early May with Agway 10-10-10 fertilizer.

The first photo show Utah Giant alone with a branch of Bing extending into the photo from the right that has a bit of the same problem but only on that particular branch that overlaps Utah Giant.

The second photo shows Utah Giant toward the left with, iirc, Bing, Stella and Lapins on its right.

The third photo shows the row of cherry trees ensemble with Nadia plum-cherry hybrid on Citation at the end. The cherries are all on either Newroot-1 or Gisele-3.
