Lost one of my first true leaves, could use some advice please!!

Hey all. So I just started a grow ten days ago, just one plant for the time being. She has proper lighting and seems to be responding well. She is very green, no discoloration whatsoever. However, last night one of her first true leaves just fell off, it was also very green and healthy looking.

So my question is, can she be salvaged at all?
