|What's wrong with my Thai basil? The edges are kinda metallic looking|
(not showing very well here). It's wilting. All happened very suddenly,
and only to one of four plants (two in this same pot).
What's wrong with it? Should I remove this plant from the pot? It was doing so well, and the trimmings look perfectly fine in a glass of water. I don't want whatever this pest or disease is to kill its pot-mates (another Thai basil plant, parsley, and cherry tomatoes).
The only insects I've seen in these pots have been scarlet and green leafhoppers. I've read that they can cause damage to plants by spreading disease and sucking the sap from the stems, but this all happened very suddenly.
