Not sure whats going on...help...pics

Looks to me like your little seedlings are turning purple because of cold damage. When a plant gets really cold it will flush the green chlorophyll out of the leaves, turning them purple. Hence why plants in cooler climates sometimes turn completely purple in the cooler months around harvest time. But don't you worry, i don't see any sexual organs on her yet, so I am pretty positive she is not flowering already. As for your first plant that is already flowering, how did you stress her? You should just make the best out of that plant, because It is already that deep into flowering. It is at the point of no return. Just give her some TLC. Her yield will be much smaller, but with a little love, you can still get some bomb ass bud!
Hope this helps ya man!

 

Had some cold weather in Mich and same thing there. They should be fine.

 

im in michigan too, haven't put my babys outside yet there still under a 24/0 cycle andd im going to veg them until the day is about 13 hrs.

 

Yeah that would be ideal. Put mine out about a week ago. Hardened right off the rip. It'll be a good test for em. Still healthy just slow growth until they get set then off to the races.

 

Yeah, I heard you all have been having some shitty cold wet weather in cali, but hey, just be happy you don't live in NY where I have to deal with it year round
Once again Best of luck!
