Although they are growing something is off. They look pale,
@Spike_KCanG is right check those things, 99% sure the PH is off.
@oldskoolkool is also very right, clean the tent to prevent bacteria and mold. It may not seem as a problem now but in flower it can get to be a problem. Plus is always good to keep it clean.
Keep the enthusiasm and keep on growing , learning and enjoying the gifts of your labor 😁😊
