Well, several things come to mind. First, curling or folding leaves is often caused by either not enough or too much water. I wouldn’t think you should need to water three times a week, unless you’re not watering deep enough in the first place. If you’re sure that you are watering deep enough, then you may be watering too often.
Another possibility is lack of nutrients. The organic Miracle-Gro soil you used contains very little fertilizer. Many of the nutrients in organic soils have to be converted into inorganic forms by soil bacteria and fungi before the plants can use them. For that reason, the nutrients are typically released rather slowly. You might try giving your plants a little Miracle-Gro water soluble, all purpose, plant food to see if that helps.
The third thing I’m wondering about is that white wall the plants are so near. Could they be getting too much reflected heat from that wall?
Hope something here is helpful,
