Hi, several factors could be responsible.
1] render mix was wrong
2]first coat of render was'nt scratched or final coat was put on to quick.
3]sub-standard sand was used which would account for the salt staining [white substance] your seeing.
Knock it off and do it again correctly, if it's blown it should come off easily.What sort of blocks were used for the walls?
