Photoperiodic is going crazy

It's most certainly entering flower, Few things could be at play: 1) The seller messed up and send you auto beans and not photoperiod. 2) your light timmer is not what you think it is. 3) you mixed up the beans with other ones you have on hand. 1/ should the seller have shipped you the wrong beans message them and ask what they can do. Maybe send you the right ones or give a credit on your account. I would not expect a massive show of support though, most seed banks don't care. 2/ This is one of these is easier to troubleshoot then the others. If you light timer has multiple on/off functions check them all. I messed up on my grow like that as my digital light timmer has 20 on/off functions and a random mode. 3/ This only works if you have other seeds to mix it up with. Very good point by Scrubbyjimbob, when new Fast versions of plants are made some of them just go auto vs fast. New Fast versions being a Photoperiod plant mixed with a autoflower plant. Old fast versions before autoflowers where 100% photoperiods they just happen to ripen a bit faster, normally by 1-3 weeks Good Luck!
