Variety - Lipstick (pimiento type) - this is the only variety that it appears to be happening to.
The peppers are fairly close to the ground, higher ones haven't developed much yet.
Haven't seen any critters on the plants. The white spots are fertilizer splash.
I have that on one particular variety of pepper- my favorite, of course! It looks like the little white fly got to it. They are tiny, tiny. If you shake the bush it almost looks like ashes are coming off. I did notice that if I plant my peppers amongst cuban oregano- very aromatic, the bugs stay away. Also, we crumble a cuban oregano leaf and and rub it on our legs to repel mosquitoes. You smell like Italian salad dressing all day but who cares!
If you go for the pesticides, make sure you get one with a "spreader sticker' AND spray the bottom side of the leaves too. I don't have a "preader sticker so I have to spray every other day.
