Note how the discoloration is focused around the leaf veins and the edges and leaf tips? That's circulatory damage and the most likely cause is excess nutrient damage. Skim off what you can from the soil surface, flush through the containers with water, and monitor. You will likely lose those leaves but the new growth should be ok. Next time go much easier on the supplements - even organic supplements can easily burn plants - especially container plants and all that excess nitrogen will only get you big bushy plants with minimal production anyway.

My peppers ( along with 95% of the garden) were decimated by snails/slugs this year. The snails outright killed all the tomato, squashes, lettuces, cukes, melon seedlings by eating the starter leaves. I'd plant a sprouted seedling and the next day would come out to a leaf-less stalk that never produced another leaf! The peppers they harmed and made them stunted. They chewed around the stem in a circle. So the stem is half the circumference at ground level as it is at the 3 inch level. They also chewed holes in the leaves. I never saw the snails and slugs till I went out after a rain and it was almost dark. They are nocturnal, as far as I can tell. I tried hand picking them but got discouraged when I picked up 200+ and went back to the 1st row in the garden and there were just as many crawling ones again! I bought Natria at a Lowes store and it's a slug bait that is organic- approved. It's iron phosphate and the slugs eat it and overdose and pass away. It works extremely well, if that turns out to be your culprit.

Yes, I agree with DON, if you are growing indoors, I think lighting is probably the problem. However, even if the leave at or above the pepper fall off, I dont think the pepper pods themselves will be affected....that is if it is a light issue. Getting some light to the sides might help...maybe some type of reflection system. Also, spreading your plants out a bit might help too. Or, better yet, get them a little real sun...Unless you are in Australia or the artic circle, this is the heart of the growing season outside. If you got that route, just make sure you harden your plants off properly. Maybe a photo of your grow setup will help. Bruce

Thanks for the reply and that may be right, I don't recall getting them wet but something could have splashed on them, it did seem to happen after they were set out in full sun for the day unintentionally... ie it went from overcast to full sun while I was at work and my peppers were exposed.
