white spots on my plant? anyone help please

Hi guys just got my 1st two young pear trees and quite a few leaves have these white spots on there are they a concern ??
.

 

No, don't worry! Could be a result of water and strong sun on leaves, or chemical residue, but neither will do long-term damage. What you need to keep an eye open for are red blisters on leaves or blackened tiny fruits that drop. Both need to be collected and destroyed asap.

 

thanks
