For sure keep growing it and it's a learning experience. Focus on the things you can do like properly watering it and maintaining a good environment with the proper humidity and temperature. Once you get a better light you'll be glad to have the grow area stabilized with consistency in your temperature and humidity. If you don't already have one you're going to need a humidifier and a dehumidifier depending on your area. A good fan for proper airflow will also be a necessity. Getting started isn't cheap but the bud you grow will be better than the commercial stuff once you get the hang of it. It's worth it as long as you're going to stick with it.
