I know it looks like it is stretching and leaning.. I just don't think I put the seed deep enough into rockwool. Looking for feeeback.. Seedling is about week and a half old. Maybe 2 weeks.
To me it looks like it was damaged half way down the trunk. Also that there was some issue early on, as evidenced by the yellowing of the cotyledons (first leafs). Make sure it's getting some movement from a breeze and fresh air.
