Your tips are not really pointing like the image. Correct me if I am wrong but, the common cause of that is Nitro tox. That seedling looks fine. I don't tend to worry about leaves hanging heavy and if you ever severely underwatered a plant and the leaves are pretty much verticle, it will still bounce back. I get worried when I see spots, or something working its way out, up, or down. Less is always better with cannabis.
