The first 2 pictures are bhut jolokias from cross country nurseries. I got them in the mail 2 months ago, and they have done practically nothing since. They started out in Sta-Green potting mix, but quickly realized how terrible it is and took them all out and mixed about 1/3 of the Sta-Green with 2/3 pro-mix and some mircale grow (regular), plus some extra vermiculite and perlite and bone meal and some foliar epsom salt. They didn't spend much time in the Sta-Green, only a week or two. After I repotted them they started to take off for about 5 days and started growing again. Then, they just went dormant again for the past month. My other CCN plants (red savina and scotch bonnet) were similar, except once they took off they kept growing and still look pretty good.
Overwatering was an issue with them early on due to all the rain, but they haven't been overwatered for a solid month. They have been given 3 or 4 very light fertilizations of fish emulsion, bone meal, and MG, along with a lot of foliar spray of epsom salts. I haven't been able to spot any insects anywhere on the plants with the naked eye.
The last picture is a trinidad scorpion. I'm not overly concerned with it, since it is growing pretty well. I transplanted it only about 2 weeks ago and it was pretty small. The color concerns me a little since it's a pale green and not the dark green of most people's plants. I added bone meal and epsom salts (foliar) but it just won't green up. I only got it ~3 weeks ago and it won't green up. I have numerous other chile plants, tomatillos, and tomatoes in the same soil and conditions that are thriving, so I'm not sure what is up with these plants. The bigger jolokia appears to my untrained eye to have a fungus or virus or something but I don't know. The smaller one I don't know, it just won't grow.
