My Plant Fell to One Side and the Leaves are Now Resting on the Edge of the Pot

When I went to sleep, it was fine and growing upwards when I woke up it had fell to the right side and is leaning on the pot now. It's not snapped its just growing awkwardly now because when I push the stem back to its original position the leaves are now facing sideways... it's about in its second week of veg. Wtf happened to it? and what should I do? Thanks in advance

One of my girls had a similar issue starting out. I found her laying FLAT on the rockwool she was in. After the light cycle tho she seemed to perk up. Pics are appreciated

I would have put one up but I don't have a camera :/ I've gave it some support by putting a stick in the pot but what do i do about the leaves? Now that its been at the right of the pot, when I put the stem back in the center the leaves are basically facing the left wall now... Mine wasn't leaning it was lying flat aswell, nothing snapped though so she isn't dying just growing awkwardly now
