I have three pepper plants, two scorpion opera (Trinidad and moruga) and one ghost pepper plant. One of the scorpions and the ghost pepper seem to be turning yellow and are dropping their blooms. My other scorpion is doing fantastic. They all get watered the same, get about 12 hours of sunlight, and are seeing temperatures from 55 F to 90 F, depending on the day or night (I live in central Texas). Any idea what’s going on? I can’t decide if it’s a nutrient deficiency or nitrate toxicity, or maybe it’s something else entirely.

This pepper plant is the one doing good.

This one is the other scorpion, which has some obvious yellowing.

This is my ghost pepper, which seems to be doing better than the other scorpion, but still doesn’t seem to be doing as well as the scorpion in the first picture.

Here’s a picture of all three of them, with the ”healthiest“ one farthest on the right, with significantly greener leaves.

On a side note, does anyone know why the leaves are somewhat bumpy and crinkled on all of them?
