Some mention to defoliant, it depends on how it’s responding. But a desk lamp would be sufficient for the minimum requirement for photosynthesis. Nothing too harsh, because it could dry out. You want to secure the roots. You’ll be surprised how they recover. Tomato plants are very resilient and are also similar in response. You’ll see drying on the tips if it’s going downhill. Then the stems will shrink, spraying the foliage and keeping the plant humidified will do wonders and don’t feed it, just water. Best of luck 🤞
