Sorry guys, this might be in another thread but don't have the time to search....anyway, this plant curls up into a lettuce/cabbage ball type of thing at night. Lights out is at midnight and about 11pm it starts to curl downward....weird....shouldn't be cold, we have a well built room with excellent temp control...we have another plant going also but it's a diff strain...no cabbaging going on with it....please help...
