give her more light
put her on a stick till she gains some strength and make sure the roots are comfortable and have grown a bit
then when she starts growing nicely a bit, fim her.
good luck. this is a clone yeah?
I correct stretching by repotting the clone and bury the stem within 1/2" of the top node when possible. It also depends on where the plant is in the cycle. Hard to say without a photo.
