Have a plant which i keep in water in a vase and change the water every

roots thick white strands.
Recently the leaves are becoming a bit pale, so I guess its short of a
nutrient or two.
A long time ago i heard that putting a copper coin in the water helps to
provide nutrients. True or not i don't know.

Copper isnt a useful nutrient for plants

Are there any other simple things you know of, that i could put in the
water
that would provide nutrients and still allow to me to change the water
easily each week? Thanks.

plant food, compost.

I should have explained more carefully about when i said: allow me to change
the water *easily*. Since i put in fresh water every week, it would mean
messing about with adding new food or more compost each week.

Just get some liquid houseplant food, sold for the purpose and add a
few drops as directed when changing water. You should be able to buy it
in any shed, GC or some supermarkets.
