Hi
@rusga! Seedlings are stretching because they're searching for more light, you must decrease your plant<--->light distance to stop them from stretching. More light efficiency = stronger plants + more nodes + more side stems. Be careful however, your babies might suffer from light-stress or heat-stress if the light is too close. Now, I won't recommend any manipulation/surgery until they have become taller/stronger/healthier, give them a few days to recover after your setup adjustments. Hope this will help, keep us up-to-date and happy growing 👊
