I don't have a lot of experience with hydro, but if I were to take a guess, it looks as if your lights are too intense. You may want to either raise them some or dim them down. At that stage, they don't need a whole lot of light and those QBs you have can be rather intense.

Do you have roots in the soup? If so are they wimpy ass threads? Start pouring solution through the top like you’re watering soil.

Is there space between the bottom of the netbasket and the soup? If not there should be.

There should be an inch of clearance. There should be adequate roots hanging down in the soup to transport the soup. Pour the solution through several times a day until growth starts.
