new growth wilting!!!

on all of my plants the new growth is wilting or looking a little brittle and wilting down. anyone any ideas. the wilting begins on the leaf edges

are they curling inward? how old are they?

pics? age? soil?

Sounds like heat stress or low humidity.

i kinda think i am having the same problem. I woke up this moarning to check my plants and noticed one looked very bad. They are all nearing harvest by a week or so. It has been hard however to water them the past 2 or 3 days due to personal issues and as i said today when i woke it was too late. the plant seemed as though it was completely dried out, fan leaves turned yellor and crinkly and the bud was light , losing its green. i feel as though this has been from not watering and the temp was up to around 90F. a serious day blower. I watered thouroughly and after a couplke hours not much has improved, is this crop done for or does it somehow have any chance?

maybe be more clear with your setup and where you are in the grow

mine have been flowering for around 10 weeks its in a closet therfor has poor ventalation with a 400w hps bulb, its been around 8= hours since i last checked them and they seem no better than before it seems as though they decresed their weight by by half, when i got to them the temp was more intense than usual and they had poor wateringto say the least. i really think theyre done for. wel i dont think they will get to the stat they were in before, after theyre harvested its going to be some very light bud, i dont understand before this happened it seemed like i was going to have way over an ounce off the plant and now it seems like ill get almost a ounce if im lucky :[
