And help again please.
What ails this pelargonium? Nothing exactly matches in my Pests and Diseases book. It is affecting all three plants in a trough. They look healthy otherwise and are beginning to flower nicely.

Might be pelargonium virus, or just plain old leaf spot, assuming there's no sign of rust beneath any of the leaves (I can't see any on the back of the leaf in the pic). If the plants are growing well, even if it is the virus, let them alone.

That's good news! I just hope it doesn't spoil the plants as they are looking so healthy.
