Green to Growing

Good Day Everyone:

My babies are 6 days old, and I transplanted the plugs I had sprouted my seeds in since the roots were starting to show through the plug. I noticed the change in color (slight lighter in green) and slight burning on the edges of the first leaves. I'm thinking this could be due to two issues. One, my light may have been too intense and too close to the plants. Or two, the soils I'm using may have had nutrients which may have been too much for the new plants. My water Ph was at 5.5 and I have only watered one time so far. The plug was still moist when I transplanted and I premoistened my soils in my new pot with the adjusted PH water prior to planting. After planting, I did give adjusted PH water to help settle the soil, but the soils are still quite damp and the fiber pot is damp to the touch on the exterior. Temp at the plant is 75°. I've been placing the Dome back over the plants at night to help maintain warmth and humidity when the light goes off. I've been taking the dome off for the last two days to help give the plants fresh air and help to evaporate off any excess moisture. Are my babies going to be okay? Do I need to take action to keep them alive? Any help would be greatly appreciated.
