Mottled, spotted, wilting leaves. Garden Centre employee confirmed some kind of fungal thing. He gave me a spray but I think they're gonners.
But why?? Grown from seed in new compost, potted on correctly, watered correctly, were flowering and beginning to produce. Behind south facing glass, admittedly very warm the past weekend or two. Not yet put outside. Then suddenly, like over a 24-48 hour period, they started dying.
Wondering if they just got too hot/had minimal airflow?
