You need to give them around 8 hours of direct or nearly direct sunlight every day. If you're in the northern hemisphere, your porch or balcony would need to be facing south for them to get the amount of light they need.
If it were me I would add some extra coco/soil whatever you are using just to support the stems as they are long and not very strong at this stage but they are definitely coming on 🙏🌱💪 💪
