If you have a Lemon tree and can keep them with lovely green leaves
,then can you tell me what feed you use& what water .

You may be feeding too often then. Patches of yellow indicate the plant
is struggling to find enough iron or magnesium for chlorophyll.

Or overwatering. Citrus do not like that.

That is the most likely cause - which I had overlooked. I never
overwater anything. I've had citrus wilt on me and shed a few leaves..

The cacti and succulents don't mind so much.

It is a bad idea to use tapwater on any lime hating plant (although I
do sometimes for my blueberries when I run out of rainwater).

Most citrus aren't really lime-haters, but don't like alkaline soil.
I water mine with tapwater a lot of the time with no trouble, and
most people classify this water as hard. I don't, having lived in
South Wiltshire, but Cambridge water is definitely not soft.

Softer than limestone regions but not by all that much. My water is
fairly hard and lime haters do not do well on it.
