I'm running 18/6 veg light. Three weeks in veg (about the time they started stinking) i have noticed three hours prior to night, the plants start drooping. When this occurs, they look extremely pitiful and sad, very sad. It just started happening the last couple days and temps/rh have been the same since week 1 of veg. However when the plants wake up, they look extremely healthy and perk right up. There are many threads regarding this topic, but i have yet to find the exact reason why. My natural thoughts are this is normal, as the plants have learned the light cycle. Around three hours prior to drooping, they are exhausted from the days light, and are literally getting ready for night time. I could use some expert opinions on this topic. I have thought about changing my light cycle to 16/8.
