I am a bit paranoid about needlecast. Those all look like this seasons needles, are there two flushes? Hard to tell. What were the old needles like? Also, new plant to OP set off alarm bells. There do appear to be bands in the middle of some of the needles, but Frank has way more experience than me, so I would follow his advice.
This is a very young tree that is exhibiting some stress and looks like it is weaker. Smaller new buds have struggled. Typical results when attempting to develop without retaining enough branching and foliage to keep the tree vigorous. The only course of action at this point is to fine tune daily care and get the tree healthier. A healthy JBP will have two, three or even four flushes in a long growing season.
When one chooses to reduce branching and foliage they run the risk of weakening the tree too much, at that point insects and disease can have a negative impact. De-candling early in development can have adverse growth effects as well. The tree's health looks like it is
being worked to much too early in development. If it was ready for reduction in branching and foliage there would be more evidence off substantial base, flare and other characteristics of maturity!
If the tree were in my yard I would grow it out for at least three or four years and focus on keeping it healthy! I would probably explore the root base this coming spring to ensure it has the best chance of recovery to good health before proceeding in development.
If I knew the complete history of work done and when then I could put forth a more detailed plan.
