Wilting a lot towards end of light cycle - 18/6 autoflower

I have had a couple autos do this. I think they are putting themselves into sleep mode because they aren't happy with the light intensity. If you notice the leaves getting any damage then I would cut the lights back a couple hours. Other than that, it's nothing to worry about

Can't say if he's wrong but matey saying its normal due to light hours is a new one on me.Iv done a few auto's and never had this issue.Like the other guy said it looks like drying out to me.Are you feeding her enough.Flush her just before your next feed.Give her several litres of plain water then feed her,do it at the start of lights on then see what's she's like at the end of the day.She looks big so she'll certainly be thirsty a thirst gal.

110% ----------------------------------------- This happens a lot, its pretty common cuz the plant has evolved under a certain light schedule when being bred by the breeder, some plants when they are sold as a seed then have the tendency to get droopy leaves right as the light cycle is about to finish up everyday. This is a symptom of adaptation, the plant is getting too much light hours, and she will adapt, she moves the leaves downwards to "prepare" for night time and take her rest from the huge day of growing she had on her, it just means she is refusing to uptake those last minutes or last hour of light because by that time she has already gotten all the light she needed for the day. You can reduce the light hours slightly, but i would not do it IF you have other plants under the same growlight. Or you can just move the light a lil tiny bit upwards, but i wouldn't do that either to avoid stretching. Sooo... just let her do it, its not harmfull and she will keep on doing as she has done. ----------------------------------------- stay lit growmie.
