Please help, I'm new to growing and i have no clue why this is happening. I have a week old plant and the coltydeon leaves are yellowing curling and dieing i have a 25 watt CFL light on it. I had it around 1" or 2" away from it but then noticed the leaves yellowing so i moved it up to around 5" away hoping for a change. I know the coltydeon leaves are so posed to die and fall off, but this early?

Oh any by the way all the other leaves are fine, along with the stem

those are supposed to fall off if the rest of the plant looks fine then there is nothing to worry about, the next to go will be the single bladed fan leaves that are ust above them, it is normal for leaves to fall off at the bottom of the plant, especially the little seedling leaves so dont worry
