I have a plant that is about 2-3 months old, has a total of 14 leaves, and stands about 7-8 inches tall. However, recently I've noticed that some of the larger leaves are curling. They aren't browning at all, and look healthy except for this. Also, I had to switch from a halogen bulb to a flourescent one recently, and after a night of the flourescent bulb, the two smallest leaves (not the round ones that are supposed to fall off) are yellow/brown, thinner, and curling in on themselves, whereas the larger leaves have been curling out. I'm mostly concerned about what caused this sudden yellowing and curling of the smallest leaves, and how a change in light could effect so drastic a change in plant health.
