Follow the vine back to the pot
A yellow leaf on the end of a long healthy vine may have a different cause than yellowing near the crown. Check whether the affected vine has bare internodes, soft stems, or roots crowded into a nursery pot sitting inside a decorative sleeve.
If the soil is wet several days after watering, treat the yellowing as a dry-down and light problem first. If the soil is bone dry and pulling from the pot, rehydrate evenly rather than giving tiny sips that never reach the center.
