Chili plant troubles
I have a chilli (rather than the country as I have just realised )plant of the Masquerade variety (the ones that grow purple before maturing). I have had this plant as a house plant for 3 years and it has been fine but all of a sudden the majority of its leaves seem to have dried up and started to fall off. There are a few that still feel soft and fleshy but are wilting fast. I live in a loft room in a student house so having a dormer window means that I can't have the plants right by the window and I only really get the sun (on the rare occasion it is out) in the afternoon. It has been fine for 13/14 weeks in this room and only over the past week or 2 have I started to notice a decline. I'll list features that might help with providing an answer.
1. Majority leaves have dried up but stayed dark green (don't think its a nutrients thing)
2. Stems are still largely green but some are browning at the top.
3. There are a number of seedlings growing around the base of it. They are seem healthy and are showing none of the same symptoms (3 litre pot).
4. Light in room isn't great, not a huge amount of direct sunlight getting to the plant.
5. Generally watered when soil begins to feel dry
Any help or advice anyone could offer would be much appreciated.
