Everything looks fine. If you want it to continue to grow well, be sure to read the basics regarding growing. You'll find this information in our "Resources" area. Also, if you have any specific questions concerning what you read, you can do a search, or ask us to help you along.
For growing, you need some basic equipment. One such thing is the pH meter. A digital pH meter is recommended and is very important for healthy plants. For the longest time I skimped in this area, and my plants and I suffered because I didn't want to spend the money. Don't underestimate the importance of proper pH.
Good luck with your grow.
