more likely mineral salts crystalising on the surface, probably due to a water leak above. Scrape some off and drop into a small glass of vinegar. Do they fizz?
What is above? Roof, bathroom, pipes?
Which bit is the ceiling?

Its a problem from outside when its terrible rain once suns out i then get more peeling. Its below the over flow pipe from the bathroom and above the kitchen window.
I actually had a small drop of water trickle from the cieling edge vety scary but its dry now theres no rain and baths not making it worse.

I don't know what that photo is.
Show us the pipes that are (probably) leaking, and what they attach to inside the house.
It is useful to put a hand or coin in your photos to show scale, and indicate which way is up.

32 years when i had my roof relined they could see down inside. The only good thing being now summers due and its on my house all day dries everything out.
This mould or poss leak is on the bottom floor so the walls above in the bedroom are fine its definately between the 2 levels so far its only removed years of paint not harmed the plaster and only above the window and edges.

Its necessary to find the cause of any water/moisture damage before any repairs.
Your plaster is damaged - plus the outside corner usually has a metal angle bead that will be rusting - maybe caused by penetrating damp over a long period.
All damage needs hacking off back to masonry and re-doing, the angle bead will need sawing off & replacing.
If the CWI is indeed bridging the cavity its usually removed.
