Weird brown spot?

Hello, this is my first grow and one of my plants has this really weird brown spot. Can someone help me out?

whoa that is so crazy.


anyway, tell us more about it. What soil? What are you watering with? Did you happen to maybe get water on the leaf during a feeding? This would burn the leaf. However, your situation looks more like a deficiency or burn from a chemical.

Its about 10 days old I water it with tap water, the dirt is old miracle gro from a bunch of potted plants I mixed up, and there's a 26w cfl in a reptile lamp right above it.

looks like that tip was sitting in wet soil for a minute after u watered it

I thought it was something like that too but it doesn't come off, could that happen if the plant touched the light?

Wherever there is brown, it means stress. It could be underwatering, or like bulla said, if there was a clump of wet soil on that spot for a while.

I know i don't under water it and there wasn't ever any dirt on it
