What is making bottom leaves and flowers yellow and drop off of my pepper plants?

Question

I purchased two Carolina Reaper pepper plants and two Ghost pepper plants. First time attempt to grow these fire bombs. The ghost peppers are doing fine, producing peppers. The Carolina Reaper has started losing leaves and flowers. I read this could be from lack of water or deficiencies in nutrients. We have had unusual amount of rain this year and I have applied Miracle Grow on two occasions. Plants are side by side. Any ideas?
