Growing right or stretching? Day 5 above soil.

I wouldn't say it's anything to overly worry over, she just stretched a bit to get the light she wanted. Take notes or refer back to your diary next grow and start the light a bit closer.

at that young stage of life you can actually bury some of that main stem under more soil and it will grow more roots However as the others have said its the light intensity or lack of it that is causing the legginess in the first place Lower your light or bring the seedling closer to it by propping the pot up on something Good luck mate

She is stretching a lot. She needs a little bit more intense lighting. Move light a few inches closer.

IMHO she is stretching badly
