I looked closely, and if you are concerned about the possible speck at the end f one lobe of one leaf, then you are mothering your plant a little too much and will probably end up overfertilizing it at some point in it's life. Stop, take a deep breath, and relax. Your plant is fine for now. It looks good and green without any obvious issues. If any issues DO happen, they will happen very slowly and might not be noticed right away. It is good to be vigilant, but not to the point of fretting over every issue that the plant goes thru. As long as you keep doing what you are doing you will be fine. Don't overwater and don't worry about feeding it for at least 10-14 days, and then go easy on the food... it is still small and requires just a fraction of what the manufacturers usually recommend. Once you re-pot it into a bigger container and it triples in size or more, then you should gradually increase the fertilizer... but still go easy on them as overfeeding is the #1 cause of failure. If your soil already has fortifications and additives in it, don't add more fertilizer until you really need it. Keep up the good work, don't over-fuss over it, and go easy on the feedings and you will be fine. I could give you a foolproof mix and feeding schedule that you wouldn't believe it would work, but it does. Less is better, especially with a new grow until you really get your process down. By then you should have enough experience to know what is and isn't a good idea. Keep up the great work!!
