Young plant weird yellow/white spots on leaves

Absolutely normal for young leaves, they often can be a bit "funny", but by the time they get to their third or fourth set is when they really sort themselves out. At this early stage you have nothing to worry about, no plant will ever have 100% perfect leaves, 100% of the time. As long as she keeps growing at a steady pace, you have nothing to worry about. Hope this helps, Organoman.
