Leaf issues usually point to one of these problems:
- Yellow leaves from the bottom up: nitrogen deficiency. Increase nitrogen in your feeding schedule.
- Brown, crispy tips: nutrient burn. You're feeding too much. Reduce dosage.
- White or bleached tops: light burn. Move your lamp further away.
- Spots or patches: could be pests (spider mites, thrips) or fungal issues. Check the underside of the leaves.
- Curling leaves: heat stress or overwatering.
Diagnosing from a distance is tricky. Send us clear photos (top and underside of affected leaves) along with your setup details for a more specific diagnosis.
