Pepper seems to be losing its skin
You’ve got me with this one - I’ve just been to look at my peppers but my stalks seem fine!
It doesn’t sound like any of the obvious pepper problems, the only thing I can think of is that the stalks are growing quickly to hold the weight of the growing peppers and it may be that this is how the stalk grows to cope with the weight.
Sorry couldn’t be more helpful but if your peppers are healthy and taking up plenty of water I wouldn’t worry about it.
