Hey guys, one of my plants developed this black spot overnight on her leaf. Any ideas what this is?

Did you possibly spill some liquid on it ?

Nothing except maybe some water.

Kinda looks like 1 leaf was overlapping/touching another perhaps?

5

So, maybe no a deficiency after all?

I think your ok.
Looks to me a dark green color.
Just keep an eye on it for a few days.
