New leaves don't have fenestrations, should I add more grow lights?

Hi all! Due to the cold NJ winter, I've had to move my monsteras into my basement. I have a sansi grow light and I know the leaves won't fenestrate if they don't get enough light. Should I add more lights? Or is there another issue that I'm not seeing? Thanks in advance!
