White powdery shit!?

Hi guys, ive had a couple plants get white shit on the leaves, it started on 1 plant, i cleaned it off with a damp sponge but it has appered on another. I done the same for this plant and just wiped the leaf buh its gone all droppy n life-less :/ Any1 know why? Heres pics:

The first 2 pics are an Auto berry ryder effected 5/6 days ago, the AKS (vvv) Was effected yesterday but much worse than the Auto. The Auto didnt droop like the AKS. Its just the 1 leaf on the AKS aswell :/
