Spots on my Grandaddy Purple

I’m a newbie! Some of the leaves on one of my 8 week old Grandaddy Purple have leaves that are yellowing and others have developed spots. They are growing indoors. Just need to help identifying possible causes. Hopefully pics downloaded😊

You’ll have to wait for the photos to fully upload before posting. We can’t see them.
