Could be a bit of moisture build up and your lights just roasted that spot slightly. I wouldn't worry unless it starts to spread or you can see it from underneath. Happy Growing!

How dark is too dark?Are these looking too green? I’m not seeing any N-tox clawing but they are pretty dark, growth is pretty vigorous and steady though so I don’t know. They are in a pretty rich organic medium.
