Ghost pepper leaves falling off, curling under
Hey everybody, I have a young ghost pepper and the leaves are falling off towards the bottom of the plant, also the leaves at the top are starting to brown and curl under. At the top of the plant there seems to be different buds growing. I water whenever it seems like the soil is dry. I just recently started using a fertilizer, 2-1-6 flora gro i use about a 1/4 of a shot glass along with watering. I only fertilize once a week. I have a halogen bulb on the plant since it's too cold to keep outside right now also the plastic pot is sitting on a heat mat. Just to give you an idea the plant is only about as tall as a coke can, but getting taller rapidly it seems. Any suggestions or info?
