What is happening to my Japanese maples??? need help!! wilting, spots,

I just bought my first house and have been enjoying adding new japanese maples to the property, the trees in concern are my peaches and cream, autumn moon and beni makio. they have been in the ground for a coupple of weeks.

it looks like there is maby "burning" to edge of some leaves and spots along with spotting.

they are planted in where i would call part shade, the dirt here has some clay but i mixed with topsoil and a little sand and appears to have good drainage

has been raining alot tho

Have had a great time sculpting the yard and hope the trees make it, thank you for your help!!!!

 

Have a look through this.

Thanks for the reply, looking at the images on that link i am thinking it may be leaf scorch, the autumn moon seems to be the most affected. it may be getting to much water with all of the rain, shouldn't be getting to hot where they are located. its stressful seeing the unhealthy changes in the trees.
