Kush Four Seasons (4 Different Kush)

Omg sunday again. I have the feeling this plants don't wanna grow. I overwaterd them as it seems because some leaves are curling downwards. I hope that I did not stun them. I actually wanted to repot them like tomorrow or the day after in their final 8L container, but I'm not sure because they are still so small. What do you guys think, repot or wait? Watering them less now but more often. The potsize looks still fine for them. Man I really don't know if I do something wrong or if this are just super slow growing strains. It looks like a mix of both. But hey they are still alive and healthy, just small. Hope the sidenodes grow faster after topping. 😄
