I have been terrible at come back to this, I do apologise.
The reason why I asked the question was because some things were just doing really badly, and I couldnt think of why. I've satisfied myself it's not water though, as there are plants, even of the same species, inches away which are doing fine.
The exception is the lawn in patches, but I think that the soil is relatively poor and thin, so I've been selectively watering and it looks better.
Thanks anyway for the advice.
