It looks like it has enough ferts, if you feed i feel it will burn, the lighter green growth is from the overferted plant coping better in the soil.
Those fan leaves look too dark green from too much nitrogen, slight leaf edge curl from too high ferts in the soil. You specify that it was transplanted 1.5 weeks ago so probably not established in the pot yet. Too little ferts would more than likely be from Nitrogen deficiency which would be bright soft yellow leaves at the bottom of the plant.
Add ferts if you want to, this is just my opinion, but if it burns or turns dark green like the rest of the plant maybe flush next. Peace
