Depends on how much space you have left in the grow area. If there is enough room for them to get larger, pinch the blooms. If there isn't, might as well let them get some pods started, -OR- pinch off most of the blooms but let them each start a pepper or two so you have some early fruit and also some assurance that each plant is growing what it's supposed to be growing, not a seed mixup or cross-pollenized hybrid plant.
