it just looks like the cube got too saoked and as such all that water is arresting the baby roots of all the oxygen needed to survuive. try squeezing out a little bit of the excess water in the cube and placing it so it doesnt get soaked and you should be good. Its still a seedling. DONT NUTE IT!!

technaflora is a great brand. They have a lot of great nutes that work great in hydro. Its what i started out with in fact. I have found though that there are other things that are a bit simpler and I use different nutes now, but I also grow in dirt now too.
