Common Issues & Solutions

Yellowing leaves

Check nitrogen levels and adjust your nutrient mix. Ensure proper pH (6.0–6.5 in soil).

Curling leaves

Check for heat stress or light burn. Adjust lights or increase distance from plants.

Slow growth

Ensure proper temperature (78–82°F), humidity, and airflow. Check root health and nutrient availability.

Drooping plants

Check watering schedule; overwatering or underwatering can cause droop. Ensure pots drain well.

Browning tips

May indicate nutrient burn. Flush soil and reduce nutrient concentration slightly.
