This small black mark is showing on a new Thai constellation leaf. I’m hoping it’s not the start of something nasty - any suggestions?

I suspect it’s a defect or tear and will never go away but shouldn’t be a problem

Thank you

I agree it’s just a tear

My Thai did the same thing. Tore when unfurling and has kept a dark scar there. It’s been a month, and nothing about the scar has changed.
