Hey there 👋...
She looks a bit oberwatered to me. But desoite of that for seedlings 7 days old, they had abgood start. As the pre-writers mentioned,
Get a bit moore distance between lights and Damsels
Keep Humidity between 60-70%. 80% seems too high in my opinion.
And Nobody mentioned the data of the lights. He's right, forget about the Watts. You need to know how much "usable light" for your plant, the COB is emitting.
In my opinion your Damsels look very good for their age, don't overdo and relax. Take care at watering! How much water do you feed?
Good luck and happy Trails✌️.
