The new leaf growth on my Jalapeno pepper plants are tiny and then fall off. Why would this happen? I've done some research online to determine why the new leaves on my Jalapeno pepper plants have sprouted out, grew a tiny bit, and then die and fall off. I don't see any examples of my situation anywhere. The older leaves are fine and have no visible issues. They don't have bugs that I can see. I water them regularly and to one of the waterings I add a bit of Epsom salts to the watering can. I have 2 plants in one large pot and the other plant is not having any issues.
Any help/advise you can give will be greatly appreciated! I have attached a photo of the issue. Please help. I would love to remedy the problem, if possible!
