Wow appreciate all this valuable information. Good to get everyone's view on this. I know there's no one rule fits all strategy for these plants so I do tend to go by the way the plants look and how dry the medium feels.
I try as much as possible to treat them as individuals but there are times when I have to go to work or go out and its just convenient to water them at the same time with the same amount of everything. My environment is quite constant too with no major drops or increases in temp or humidity unless I change them. I'm also quite lucky that I have planted same strains that seem to be the same phenotype too so they mirror each other with very slight differences.
