I've been planting seeds and when they sprout they come up yellow? what's going on here? lack of nutrients?

Lack of light more likely.
as soon as they are upright though they turn a nice green
They often do. Until the cotyledons open they won't start photosynthesizing. There's quite a bit going on getting roots down to take in water & nutrients while also getting the first leaves out to make sugars all the time optimising the tiny bit of chemical energy that was stored in the seed. Quite a balancing act, one that I hope will never cease to amaze me. What species?
okay thanks. it's klondike striped blue watermelon
