Weird hole in stem is it bad ? What is it?

I noticed this on my stem can some one help me identify what is going or what does this mean ? Best pic I got

Looks like that node is trying to split off,interesting.Did you damage the plant there that you can remember? I would leave it alone and see what it does,gut feeling says its harmless.

U can't take a better pic? I dont know what it is i just want to see a better pic

From the looks of it your plant looks good, that looks like it received some damage at that time.
Don't worry about this, the plant is a weed.

watch that spot as buds get bigger.might split right there

It's the plants vagina
