Hi
@Cluck ! When I take a look at your picture I can see that you leaves are curling up so it is the sign of an heat issue, your medium looks fairly dry so it will be great to give them less water but more often . You may low your temperatures a bit by using a fan but don't put it too close from your plants. But I would say that your plants are healthy so you don't have to worry about their height , they will thrive by they own soon ! Hope it will help you to grow better , faster , stronger 💪👍😁
