I have been growing them outside. This is the first time I have grown coleus in containers and I was so happy and impressed with how full and beautifully they grow and had to save them during the winter. I have done many successful cuttings and as you said, brought the whole pots in after pinching back. They seem to be doing well except for this curling of the leaves. Even though that is happening, they are still growing, producing new leaves. I have moved the grow lights further away and leave them on for only 8 hours a day now so hopefully that will help. In hindsight, I could have left them outdoors longer but being new to gardening, I was afraid I would lose them as soon as the nights got cooler and so brought them in. Thanks for the sites. I will check them out.
