As a general rule, peppers should get no Nitrogen once they near blossom time. The N causes the plant to keep growing, and postpones blossom set/fruiting. A little P or K can be good at this time, but no N. (This is true for almost any annual that sets fruit.)
Frequent watering of peppers is a real no/no. They do best when stressed for water...it forces them to set fruit..."We're gonna die soon...better have babies now!"
The way I judge my watering for peppers, is to hold back watering until I see the leaves begin to curl. Then, after the sun gets low in the sky, give them a good deep soaking so the deep roots can feed. Do not water again until the leaves curl again. Shallow, frequent watering feeds only the top roots, which are subjected to the hot sun all day. It can actually kill the plant in hot weather. Deep watering will feed the deeper roots, and produce a much healthier plant, which is not as easily harmed by scorching weather. It will also produce better fruit.
