Here's how my other bell pepper is looking.

Hasn't it rained a ton where you are recently? Could be something moisture related.

Could also be calcium related. is there Ca(or lime) in your potting mix?

For now, I'd nip all rotting parts and see if I can get the soil to dry out some. See if things improve from there.

Let's see what others may say though.

I used Miracle Gro for Flowers and Vegetables, which has nitrogen, phosphate, and K2O for all the peppers I planted. I gave two other pepper plants (same size containers and same type of soil) to my boyfriend, who has them on his third floor balcony where they get more sunlight and seem a bit drier than on my patio, and his have some nice peppers coming.

Still if anyone thinks they can identify the moisture-related affliction on my peppers and tell me what to do about it, I would really appreciate it!

I would try cutting off the stem just below where that first fork is, ie just below where the browning is on the stem and where your flower blossoms were. I've just done some research on topping peppers. I topped my three plants yesterday and am trying to root the cuttings.

This video shows him topping around 3:00. Might be worth a try?

I think you answered your own question. Take the remaining plants over to your bf's or move the plants to a sunnier, drier location. if rain is still in the forecast, try to shield them. They simply need drying out. Pepper plants hate wet feet. They're very resilient though, so hang in there.

Best way to water peppers is drench thoroughly, let dry out almost to the point of bone dry, water thoroughly, and so on.

Hi,

It looks like you have Southern Blight. It is a fungal pathogen and is very common in places that have high humidity and a lot of rain.

You can spray the plants with Neem oil, it's organic, or with a fungicide.

Good luck
