Purple haze seedling (fem) 3 weeks old, recently transplanted. This seedling has been kinda odd straight from the beginning. First set of leaves were misshapen and always curled a bit down. Leaves are papery and curled, currently minimal development of branches (compared to other seedlings same age). The other purple haze seems to have similar issues although not as extreme and there is some development of branches.
Just as a point of comparison, you can see the other seedlings are looking nice and green (plus a bunch of newborns)
So what do you think is up and how can I fix this
