1. What is the air temp (both day and night)?
2. What is the nutrient temp (both day and night)?
3. What nutrients are you using, and how often do you change them?
4. Are you adding any additives to your nutrients?
5. Is the nutrient solution cloudy or clear?
6. Are you using a air pump in the nutrient reservoir?
7. Do you see any pests/insects on or around the plants?
8. Do you have any plants in soil with the same curling of the leaves?

P.S. Do you have pictures of the problem?
