weird brown spot pics.

so a few weeks ago i got this weird brown spot. it's at the edge of two leaves and looks as though if you put the two leaves together the spot lines up and creates a single spot. hard to explain.

like if you held the two together then put a brown spot along the center line. then let them seperate, that's what i got. it doesn't seem to be spreading and it's only on these two leaves.

i don't remember doing anything different before they appeared. not sure. any ideas?

Was it touching a light maybe?

COuld you have splashed some nutes or water onto the area when watering one day?

Also what size pot is the plant in?

How big or old is your plant?

it's unlikely, but possible that I splashed it. that would make the most sense.

the plant is approx 30 days since it sprouted, in a 4in square pot. 12/12 from seed.
