What is wrong with my magnolia?!

Hi, I planted a magnolia soulangeana about 1 and a half weeks ago and it has tiny white dots and wilting leaves. I planted with compost and root grow after soaking the root ball and loosening the roots. The soil is sandy with good drainage so I have been watering liberally (about 2-3litres a day). It gets sun all day. Please see pictures.
Thanks in advance

 

Looks ok to me, new leaves coming out, dont think the white spots are anything to worry about.

Are the leaves actually wilting or just crinkled where they are unfurling?

I'd be inclined to water less, once a week but a good one and only if its dry.

 

Thank you for the reply and advice! I think you might be right, leaves are definitely growing...
