Hello, I have a question about my Janet Craig Compacta. I have had it for probably about 4 months. It sits on my desk and gets very little natural light but it does get quite a bit of fluorescent light (at least 8 hours/ day, 5 days a week). I have noticed the leaf tips are curling underneath lengthwise. Could this be a sign of too much light? I can't seem to find anything on the web concerning this issue. It is still growing. The new growth is very light towards the center and then gets dark green to the tip. I try to water once to twice a week. Please help!
