Hello, First of all thanks for putting your trust in the UK :) This is one of our signature strains the smelly socks that is cheese :) now this looks to me like they are mottling or are suffering from the pathogen called Tobacco Mosaic Virus to be specific. Do you smoke tobacco in your house ? this might be the cause. Its certainly what it looks like at a less sinister guess. Ph flucations could cause similar symptoms like this but Overall I think she will pull through.
