@biird Only receiving 5.5 hours of direct sunlight will absolutely make a plant stretch during the vegetation stage. If this is a problem due to space restrictions there are many ways to remedy the issue like Low stress training, topping, and Supercropping.(I see you went and got greentape for the LST) If the plant in question is the Blue cheese bag seeds then Topping, LST, and Supercropping are still viable options because shes young. However if you are worried about the stretching on the white widow I wouldn't worry to much shes going into the flowering stage and stretching is normal and unavoidable in the first weeks of flower. To make the best out of this situation be sure to give her as much light as you can and be sure to keep up with your organic soil (mycorrhizae😍) so that the microbes properly adjust the PH. I think you will be perfectly fine after a proper LST. Happy growing Birrd hope I could help with your situation! 😎
