I have four white widow plants in week 5 of flowering. Yesterday night one of my plants encountered a serious problem. The leaves on the top foot and a half or so of the plant started rapidly dying. They would turn darker green, curl up and die. It was a pretty quick process. Probably about half of the leaves on the top 18 inces of the plant died or are dying. I trimmed off most of them, but there are still some on there so I took a couple pictures. I water and feed them every other day, but I doubt I gave it too much because the other three plants look great. The only other thing that I think it could be is that the other day I was adjusting the light and it came down and was touching the top part of that plant for five or ten seconds. It was hot at the time. I don't think that makes much sense though because leaves are dying too far down the plant for that to be the case. So far the leaves on the bottom three or four feet of the plant look fine. Does anybody have any idea what could be going on here? I'm going to go ahead and flush that plant tonight just in case it was overfeeding, but I'm still pretty stumped on this one.
