no, it's no auto, i don't like auto's. it was some seeds i've grown out before. it's about 18" tall. looks like a regular plant that's in flower, really nothing to see. it just seems to me that it's a bit early to be flowering already...
What was the light cycle that they were on? When starting seeds indoors under a light (18/6 or 24/0) you have to make sure the light cycle of your indoor box is similar to the light cycle outdoors at the time of planting them. I had to do this myself, got some clones/seeds a month ago and started them in my veg box under 18/6. For the last 4 weeks I was dropping the hours of my timer slowly so that eventually, my light cycle indoors would be 13.5/11.5 which is what it's like right now outdoors for me. If you're worried dropping the times every few days will make your girls flower, just have a half hour where the lights come on in the middle of the dark cycle. So if you have 6 hrs dark, have the lights come on for like 30 mins in the middle of that, then continue the light cycle. This has to be done gradually.
What happened with your plant is I'm assuming you had it on 24/0 or even 18/6 and after it got to the size you wanted you threw it outside. The problem with this is our day/night cycle now is 13.5 hrs light/11.5 hrs dark so any plant that goes from 0-6 hrs of dark to 11.5 hrs of dark will definitely start to flower due to the dramatic decrease in the light/dark cycles, so the plant will think it's time to flower. It will flower for like a week, then after the plant realizes the sunlight times are actually going up and not down like it thought it will begin to revert from flower to veg. Might I add that this is incredibly stressful for the plant to go through, and although you'll have a lot more budsights than before they will all be fluffy and airy.
If you can get a hold of more seeds, I would recommend starting over because now is still a good time to start seeds! I got my order from Attitude in and right now I have like 14-15 beans germinating right now. Once they pop, they go into dixie cups outdoors under a little tiny greenhouse that I've constructed. Do NOT put seedlings outdoors unless you are sure they will be safe from winds, bugs, pets, etc. If you don't have a little greenhouse that makes for safe outdoor seedling growth, find the window in your house that gets the most sunlight and put the cups on that windowsill until rootbound. Just before they get rootbound in the dixie cups I transplant them into my 20 gallon pots for the final transplant. Make sure you have fencing around them for protection, and a nice feeding/spraying of Azamax is always nice for preventative measures.
If you start from seed right now, you won't have this problem anymore since the seedlings will already be used to the outdoor light cycle since they're exposed to it on a windowsill or outdoors. If you get those seeds going now, you'll veg until the solstice on June 21st when the light cycle starts to decrease again. Best of luck man.
