One of the leaves on my orchid is curling into itself. It's the newest leaf on the plant (the other leaves are fine). It's also very thick. I've had it for about 7months now and am about to re-pot it but would really like some advice on what's wrong with it so I don't cause more damage.

I've checked for bugs but there's nothing. It has a new shoot that's just popped out (2nd pic) so it can't be dying...?

I water it weekly but havn't starting feeding it yet.

many thanks!
