Hi
@Fieldys_89! We're missing some crucial informations here, what's the medium/soil, where does it come from and what's the brand? Your soil might be too rich for such young seedlings. Have you been giving any nutrients? I see "Ionics" written above but I have never heard about this, are you using "Ionic Nutrients" by Growth Technology? Judging from what I see on your pictures, I think you over-watered your plants, roots need to be on a wet/dry cycle, in order to search for water and spread everywhere. Also, your light<--->apex distance is a bit high. HID bulbs are not supposed to burn your babies unless they touch the bulb, so you can decrease this distance to 25cm, this will help in drying the medium, and the more light plants can get, the more nutrients they can 'digest'. Finally, I can't see the air intraction in your tent, are you sure your babies can get enough fresh air / are you sure your airflow is continuously regenerated? You may need to open the small windows on your tent's sides, this will help in renewing the air and cooling down the environment. In this scenario, I'd transplant asap to a 10L container, because 5L is just not enough for the whole veg+flo cycles, then I'd increase the airflow by opening the tent's 'windows', then I'd decrease the plant<--->light distance, then I'd be very careful with waterings, giving water only when the medium is dry. Hope this will help, I'll be around, keep us up-to-date and happy growing 👊
