my bell peppers develop brown, dry spots

If the spots are on the top or sides of the fruit, then it is likely sunscald and is from too much direct sunlight. A simple shade will help stop it. If it is on the bottom of the fruit, then it is blossom end rot. This article will help with that: https://www.gardeningknowhow.com/edible/vegetables/pepper/pepper-blossom-end-rot.htm
