O.k. iI have been growing random seeds for about 3n1/2 weeks with the lights going 20/4. the plants have been going pretty good but last night the timer was unplugged somehow and the lights didnt turn on while i was sleeping. The plants got about 13 hours darkness instead of thier normal 4.... this is the second time the timer has failed on me and they recieved more dark than normal, throwing off thier schedule. My question is, are they going to be messed up? does this affect yeild, sex, ect.? Also all began to pre-flower at the nodes.. what should i do? just continue the normal sched.?
