I've been growing a Salvia 'Patens' in a 2L pot and it was doing fine

appear on the leaves, young and old. Any ideas?

Are you keeping it pretty dry and watering only when necessary? Let it
drain between watering, too and don't let the leaves get splashed with
water through which sunlight can burn them.
