Do I just have a JBP seedling with some interesting genetics that produce a yellowish coloration on the newest needles or is this something health-related? The 2 seedlings are planted in the same soil mix literally side-by-side in the same mesh bottom tray with downspout tubing risers. They receive the same care. This is their first season of growth. They were germinated indoors under lights in peat pellets during late winter and brought outside to be planted in downspout tubing in spring.
