no, the yellow leaves won't recover but hopefully the plant will recover. It was just the lower leaves that turned yellow but the upper leaves were a bit faded and droopy. It seems a bit better today.
The plant is roughly 6 weeks from germination, so it's still not very big yet.
The soil seemed pretty compacted so I think perhaps the roots weren't able to get the nutes they needed. I transplanted today into a looser soil mix and she seems to be responding well. I've done everything I can think of. The new growth looks very healthy today. Thanks for the help Fuzzy.
