I have also experienced the same thing this year. I have large lush green healthy plants, with few to no blooms. I have done everything I had done when I was living Southern California, but now in Arizona things seem completely different, weather, well water, different pests etc. This time of the year I should have already started harvesting several peppers. Two weeks ago I finally broke down and bought Fox Farm Tiger Bloom 2-8-4. I use it every other watering. I have noticed some plants already responding. Hopefully a couple more treatments will be enough to kick things in gear before the season ends. Good luck.
