I know that (generally speaking) yellowish to lime-green leaves combined with slow/weak growth in a plant are an indication of inadequate nitrogen, and one must fertilize accordingly.
However, does the same apply for a plant that is showing considerable growth but with pale-colored leaves?
Consider this calamansi (citrofortunella microcarpa):
The previous growth (before I bought it) consists of small, dense, dark-green leaves. The growth since then takes the form of much larger and paler foliage.
I do fertilize (though not too much), and the leaves are from the same stem so it's not graft vs host.
Am I doing anything wrong or is everything normal?
