I've noticed that some of my citrus plants grow unusually large spines on their second flush and well, I wonder why. Any ideas?
It is the first time my seed-grown Poncirus does it whereas my ichangensis x sinensis has done it before.

It is normal, thet could be even longer.

Most all immature seedlings have spines. The spines will continue to grow on all new growth until the tree reaches a height enough to become a mature tree.

Ok, I was just wondering why they were much larger than on the branches that were grown in spring.
-
The quicker is growth, the larger are the spines.

I think poncyrus is thorny forever no matter how old tree is. Fruiting poncyrus I've seen are large and thorny as all get out.

Yes, Poncirus is always thorny but usually they are much smaller.
