How often you watering? If your using rockwool for your starts I would only water for 15 to 20 minutes every 4 to five hours. I use an aerocloner and then go straight to hydroton and only water every 4 hours for 20 minutes. I than up the watering according to plant growth until its on 24/7. Your first pictures look like overwatering to me, which can happen in hydroton especially if you are using rockwool. Try backing off on the watering you'll be able to tell if they need more water.
