My sweet banana pepper plants are only about 14" tall and they have a
distinctly yellowish cast the their leaves (always have).

They haven't put on any kind of growth spurt, yet they have started to
set flowers and one has already started to produce a fruit -- it's
only about 1/2" long now.

Should I pinch off the present set of flowers and try to make the
plants grow larger? Would that have any effect?
