anyone have an idea why this is happening? these are apricot/peach hybrids, they are under the exact same conditions and one of them is nearly 3" taller than the other. they were moved out of cold strat at the same time and sprouted at the same time, and were separated into different pots when they were both about 3" tall. neither are sick and i'm not super worried, just curious. is it just a genetic matter because they're hybrids & not identical?
