Several things come to mind. Did you water in well with plain water with something like
Superthrive. Always use a product that has B vitamins to reduce transplant shock. Also at this point, don't overfeed. Back to watering in. You might already know, but I will explain anyway. When transplanting, it's important to overwater a bit to eliminate all air pockets that may be around the roots. Also to make sure the root ball is nice and wet. Gives your baby the best chance at a nice, painfree transplant. At this stage if you use a nice mild solution, N toxicity should not be a problem. Let your plant tell you how to feed it. A nice, healthy plant is like art, I know it when I see it. By the way, your plant looks fine, except for the drooping. Give it a good watering in again, it looks like it's struggling a little to get enough water.
Good luck
