I love surprises!
Well, they're flowering and that's not the time to transplant unless a dire emergency exists, and that doesn't seem to be the case here. It is uncertain if you are growing an auto, or a photo that was placed outside too early, like
@Oldchucky mentioned.
If it were me, I would just ride this one out and endeavor to start a new grow with all the lessons that you're learning from this one. Obviously, you do not have to wait for this plant to finish before starting again, unless time or space constraints exist.
Here's a great resource to do some reading and learning:

In the meantime, stop misting your plants. That's not necessary at this age. Misting is for fresh cuttings, and possibly very young seedlings that are not in the most correctly adjusted environments.
Overwatering is probably the most common mistake for new growers! Most will tell you to saturate the pots completely until about 10% runs out of the bottom. Then let them dry back until they are very lightweight. Best thing to do is to saturate to 10% runoff, pick up the pots and feel how heavy they are. Then as the days go by, pick up the pots daily and get a feel for how they are becoming lighter. There will be a day when you pick up the pot and it will feel very lightweight, and that's the day you water again. Obviously if you notice some wilting, then it is definitely time to water.

Take a moment to consider your water source. Is it a municipal water source? Best practice for that is to fill up your watering can or bucket, and let it sit for a good 24 hours for the chlorine to evaporate off.
Have a look around the farm here, and do some reading online and get a feel for the types and brands of soils that people like to use (If soil is your thing), the nutrients that they prefer (organic or synthetic), and come up with a basic plan for your next grow.
Finally, when you're ready to start your new grow, start a grow journal or diary here in the appropriate sub forum. There are a lot of experienced growers here who would love to help you plan and execute your next grow, giving you a much bigger chance for success, and of course, gaining more knowledge.
