Like 3/5 stated we’ll need to know more.
There are a lot of variables that could cause the no pods:
- Pot to small, roots restricted or damaged
- Not enough light or the wrong spectrum
- Over/under watering
- Bad plant strain (get into that a little later)
- Too much nitrogen
- Insect infestation
All these just over stressing the plant
Yellow leaves:
- Insect infestation
- Under/over fertilization (over usually burns the leaves)
- Pot to small, roots restricted or damaged
- Light source
The bugs, if they’re roughly pin head size I’d say aphids, so small you can barely see them spider mites, and spider mites will yellow the leaves and sometime make them kind of translucent. Aphids will also make the plant sticky, since there waste is a sugary substance.
Now to address the bad plant strain, in 07 or 08 (can’t quite remember, drank to muck beer since then) I bought 4 Bhut plants from the NM Chile Pepper Institute (CPI), the plants look beautiful tall and loaded with flowers, but I didn’t get one pod. I asked the CPI about this and (I wish I could quote, but again drank too much since… but it was something like this) they said that the Bhut was a cross between the C. Chinense and C. Frutescens and was not reliably stable and they had distributed seed to growers in the hope of finding a more stable strain. IMO this could be resolved, I haven’t had any issues since then.
All of this is off the top of my head and I most likely forgot stuff, and if I’m wrong the other members won’t hesitate to correct me.
On a side note, 3/5 congrats on the 600 post.
