Silicone paint to k render new build

[Qualityisamust]

Advise please see pics, this has been painted with knauf silicon based paint on to K rend new build. It is dry but looks like the paint is flaky but render is fine, I’m thinking to brush off and touch up with the knauf paint but want to understand why this is happening. Could it be efflorescence or lime bloom?

render looks low, have they breached the DPC?
