Hydroponic seedling problen

I’m a little frustrated as my plants in the soil grow faster, one in my dwc plant I have measured the ph value, and the ec value it is as it should be, they have had a little hard start and almost looked like this from the start on foliage, I think they got too little nutrients when they were in rockwool block, but it is now 4 days since they are thrown in dwc and there is almost nothing done. Now I have tried to turn on the bloom button on my led panel in the hope that something more will happen. Hope to help me with what happens?

Looks like your soil cups have a lot of algae and microbe growth because of too much water. Needs looser soil and a lot less water.
