one of my plants all of a sudden shriveled up during the dark period and i waswandering if any of you knew why that would happen any help is much appreciated
Could be many different things, anything from watering, to root bound, to temperatures. We would need more information.
We need alot more info than what you gave man. We need to know what strain what soil what nutes if it was from seed or clone Light regime light wattage also how close the light is would help even though this did happen during lights off. temps/humidity ph/ppm/ec is this hydro or soil? More info is needed and maybe I might can help.
