Same here. Our jalapeños and poblanos both made very well earlier, but the heat has slammed the brakes on ‘em. They’re still blooming, but nothing is setting…
Bloomset can be your friend. It is not just for tomatoes, works on pepper as well. Squash that was blooming like crazy but no quash started spraying those and have 3 small squash from the 4 blooms I sprayed.
