I bought some Big Jim Chile peppers about a week ago. Brought them home, transplanted them into new pots. They have looked really great all until a couple of days ago and then all of a sudden they are turning yellow and leaves are starting to fall off. What am I doing wrong? I live in Colorado so I've been taking them in and out everyday. We have had some nasty weather and I couldn't put them out for the entire day, just a couple hours each day.......... Please, anyone, any ideas?
