Looks fine. Iāve seen worst. They seem to be a h@ppy green and no purpling. Give them more light exposure if youāre concerned the stretching will persists.

@NorCal_kannabliss is correct just a touch of stretch but looking very healthy! When u transplant them into a pot or the ground u can bury a bit of the excess and it'll become one with the root system! Happy growing and stay lit fam.
