These are very young plants. My guess is that you have a nutrient toxicity problem. If you used a soil like FF ocean forest or the like, they have enough nutes for 3 to 5 weeks, depending on the size/growth of the plants.
If it isn't that, I agree with a root problem. Plants this small, in that size container will stay moist for a week or more and while roots are developing you don't want them to have wet feet.
I would probably repot them in one size larger pot. I'd sprinkle a rooting power over soil before placing plant in it. Then give them a week to dry out. Pay attention to the weight of them when soil is moist. Don't water again until they are markedly lighter and dry to the second knuckle on index finger.
Just my opinion.

The medium I use is tons of small mini rockwool cubes in a 3 gallon bucket. I do not have any root issues. It's very hard to get them with this medium since there's literally space between the cubes in the bucket allowing the roots a lot of oxygen. Here's a pic of my healthy root showing itself at the bottom of the bucket. I think this was a nute def because these baby's growing a lot now and all new growth is looking very healthy but we will see!
