Just want to find out if I should remove the affected pods when I see them or not worry about it. I've noticed this only on one Aji Amarillo and one Aji Pineapple plant, so far. Some of the chiles develop these brown or black'ish streaks. It doesn't behave like BER at all. The plants themselves are otherwise completely healthy with good foliage.
If left alone, they will usually go full ripe with healthy looking seeds and just have what amounts to a bad spot. We've had a particularly wet summer and I'm wondering if the Aji variety deal with that worse than other plants.
