This was planted this year
Unfortunately, your photo did not come through. Typically this is from overwatering while the tree is attempting to take hold.
Seems it’s spreading to others as well
Probably a response to the Neem oil. This should never be sprayed in direct sun, and should be sprayed on a very small portion of the plant to test a reaction before spraying the entire plant. Many plants cannot handle Neem oil.

Our 30-odd year old eleagnus, about 12 feet high and which has never flowered but has always provided dense leaf cover - is dying - the leaves are drying and falling off. What might be the reason and might it be saved? Our soil is light and well drained - the subsoil is sand. Thanks, Steve S.
Unfortunately, there are many blights that affect this species.

On the internet I see many different max heights for this shrub. From 1.5m, 2-3m, 3-4m, even 5m. On your site (https://www.gardeningknowhow.com/ornamental/shrubs/elaeagnus/how-to-grow-elaeagnus-limelight.htm) 5m is written. Is this height from experience, or what kind of source? On the label I got with this plant, it says "Fully grown: 7 years 1.5m". Its registration number is NL 21145. What is the truth? Thank you
If this is grown in container, you could expect something like this shrub to remain smaller. Once you put it into the ground, it will achieve it will achieve its full height, which can be up to about 5 meters.
Besides the black pest on fresh leaves, something white also appeared on the fresh leaves, buds (see second photo). On Elaeagnus pungens I haven't seen such pests. Nor on other plants. Thank you
This does appear to be a pest, and its larva. I am not familiar with the pests in your country, but Elaeagnus can be susceptible to a few pests.

Some of the leaves really green and some of others got silver coating only recently planted
Yes, this is normal for the most part. As long as this is not powdery in appearance.

Are Goumi berries able to grow in SW Minn.? Because it may be beneficial to my property. I am considering asking about adding them to my local Food Forests landscape if they are a good asset to have. Sorry, I don't have a photograph... A response is greatly appreciated, THANKS in Advance,CP
Not sure yet...that depends on if my question gets answered...
