I never give up until their dead. You will be surprised how well they respond to moving that light. Once they start growing through the bottom of the plug, you can transplant them into your medium of choice.
No nutrients lol. Water and that's it. Seedlings need very little light. That amount of light, that close, is pounding them into the ground. As they grow they can take more light.
What are you using for a light and how close is it to the plants? Are you using a humidity dome and opening it a couple times a day or opening the vents a bit? Using plain water right . . . No nutrients yet.
78 degrees from the submersible aquarium heater, pump pushing water through Red 360 degree EZ-cloner heads (the more the merrier). Should see roots starting in 7 days with 10mL/gallon of Clonex.
