I think she looks okay. looks more lime green than yellow. some plants are just more that color, and especially at baby stage. Looks over watered very slightly. and the tds of nutrients slightly high. Try letting dry out a little more between watering this next time, and give nice deep watering after with 20 percent runoff.. and see how the color changes.
Your photo doesn't really show any yellowing. If anything I would say she's getting too much nitrogen but not in concerning/dangerous amounts, just keep an eye, maybe back of the nutrients, or at least lower then for a bit
