Well, I decided to experiment and I have been adding large amounts of
Growmore around the roots of the Wisteria where it is planted in a 'removed
paving slab' space in the patio, then washing it in with copious amounts of
water.
Probably not the correct way to feed a plant.
However the results are interesting.
The leaves which were pale yellow are now gradually returning to a darker
green.
First the veins in the leaves turn green, then the rest of the leaf greens
up as well.
This sugests that the plant was being starved of nutrients, although it
still seemed to grow strongly.
I guess I will have to stop feeding it fairly soon, or I will be in danger
of encouraging too much sappy frowth late in the season, but it will be
interesting to see if it flowers any better next year.

You could try moving over to tomato fertiliser - still give you the
nitrogen but higher potassium to encourage flowers.
