I have a Paddle/Flapjack plant whose leaves are starting to curl. It gets 4 hours direct sunlight and around 6 to 7 hours UV light. I water it once a week. It started off perky and leaves upright but now leaves are more relaxed and spread out and some are starting to curl and bend in. Any advice would be appreciated!

What is the UV light supposed to do? Plants need sunlight - UV light is one small segment of sunlight.

The UV light is a grow light. It has helped with some of my other plants during the winter to receive enough artificial sunlight and made them grow.
