Do not even start looking at the trics for at least another 3-4 weeks. Adding bloom nutes is a good idea, just not too much. Try feeding every other water (plain water one time, nutes mixed in next) if you notice any signs of nute burn back off on the nutes a bit. At this point I would not bring them inside early, the more light you can give them the more you will be rewarded at the end. When you are just about at the point of harvest you can bring them in, or into complete darkness for a couple of days, up to you.
