Overnight change- Mini Phal leaves wilting, thining and curling

[Orky]

Hi there,

I have a problem that has just appeared to me today. My mini phal now has wilted, very thin, discoloured and curling leaves.

It is potted in sphagnum moss (tightly) in a clear container. It was doing so fine.. so sad

Not sure if it should be repotted because there are flowers in existence on the plant. One of the many flowers have wilted as well.

Can anyone advise?
PS. Not sure if this is the wrong thing to do, but i also sent this on the beginners forum..
