I just repotted these into a bonsai pine mix in 4inch platter pots, good drainage, they started inside, I let them grow outside most the spring/summer except rainy days where I brought them inside. I had a few more but they weren't even close to as developed as these so I felt these were growing pretty well. I only water once a weekish/as needed. I am cautious to not over water. maybe they need food? thru get plenty of sun. I move them twice daily into sunny areas of my house. I live in upper Michigan so winter they won't be outside...

The immature needles eventually die off as true needles grow. These trees need to be outside to thrive though.
 
Older needles do die off. In adult trees they die at around 3 years old but sometimes seedlings lose some earlier.

maybe they need food?
You have not been using fertilizer? This would definitely cause older needles to die off as the plant takes resources from old to help power new growth. I feed seedlings every couple of weeks from a few weeks old.

The new growth appears very healthy so they are coping with whatever you are doing to them.
 
JBP likely need Winter protection in present arctic location however likely to die/severely weaken if indoors.

If you're anywhere near me (Traverse City), you luckily have enough snow to offer a good amount of protection all winter. I put my trees against the southern wall of my house, and for the most part that's been fine, except for some redbuds that I think weren't going to make it regardless.

Don't store it inside, although in an unheated garage has also worked well for me in the past, but you do need to check water more often then because the snow melt won't give any.
