Grey water has a tenancy to raise your pH. I do not know how high of a pH
apricots can take, but most good plants need a pH of 6 or less (7 is
neutral). Have you done a pH test of your soil? If not, you might have it
done and see where you are and make any corrections you might need.

Our 20 year old tree has today, started to have leaves with yellow
blotches on them.
WOuld this be caused by the drought conditions as such,
or because we are using grey water?

Thanks
