The Leaves on my Chilli plants are turning yellow and falling off,
starting at the bottom of the plant. This only started happening when I
repotted them using a mixture of General Purpose potting soil from a
Gardening store and fairly sandy soil with quite high clay content from
the local countryside (Mix 50% store bought soil/50% local soil).

I repotted 7 days ago today and I've watered twice, once on potting day
and again 3 days later with no feeds or additives. There are no apparent
pests on the plants and apprt from the yellowing the plants look great,
bear fruit and are continuing to grow.

No leaves last for ever, and the older leaves, which are at the bottom
of the plant, will go yellow and drop off. How many leaves are you
losing? If you are gaining leaves at the top at the same sort of rate,
no problem.
