I've been diving into junipers for a long time now, and I've never seen a chinensis with foliage like that.
Do you know if it's a certain variety, like stricta? Stricta is chinensis, but it only makes needle foliage. But those look more broad-arrow-like than these thin pointy needles.
If there's no scale foliage to be found anywhere on the plant, I'm honestly thinking this might not get better, no.
How long has it been in the ground? And have you been continuously pruning? Because continuous pruning might cause the foliage to behave like this.
Or.. It's not a chinensis but a juniperus virginia that's acting the way they do.
