I started my tomato plants about 5 weeks ago and so far they seemed to be doing fine. I transplanted them into bigger containers about a week ago and now every one of them has wilting leaves. Its started at the tips of the leaves and wilts inward toward the stem-which seems very healthy and sturdy. I've read through other posts and find a lot on wilting leaves but they have all mentioned a slender area at the base of the stem, which is not the case as far as I can tell. Can someone please tell me what this is? A disease? A transplant issue? I could really use the help!
