Darktideanswered grow question 4 years ago Is there a better light source near bu that could be drawing your seedling?
Your seedling may also not know where the light is or having difficulty moving thru the soil if it is to wet.
Growing in a window can be difficult on seedlings and plants.
Window light is impacted by the glass and does not provide coverage that is close enough for a seedling, or a full cannabis canopy on all sides.
I would suggest adding a CFL bulb if you can to boost the light.
Great Luck & Happy Growing 🌱
