It sounds like a nutrient deficiency. An aphid infestation heavy enough
to upset the plant would cause at least some of the leaves to crumple.

If you've only recently planted it, the roots are still settling and
maybe not being very efficient. I wouldn't use any fertiliser on it
until you've established that it's getting plenty of water. Don't just
rely on the top surface being wet - it's easy to water and soak the top
inch or so, and still have dry soil underneath.

It's not going to die on you suddenly so don't panic - you've got time
to try first, more water, and if that doesn't work, some fertiliser.

Meanwhile - can you tell us more about the pale leaves? Is it all of
them, or are the new leaves still dark green? Is it the whole leaf, or
are the veins dark green with yellow bits between?

If you want to you could use a weak liquid feed in the water you give
it, but when you water use a bucket and give it 2 or 3 buckets full,
applied slowley so it soaks in to the ground close to the tree.
