Yeah don't use Miracle Grow... its not friendly to pot plants and doesn't provide what the plant really needs. Get Fox Farm or Technaflora's starting kit. Fox Farm you buy 3 different bottles... $12-15 a quart.. Grow Big (nitrogen-based for vegging), Tiger Bloom (kind of a bloom booster... use during flowering), and Big Bloom (high in phosphorous... used during flowering). If you buy the Technaflora starter kit, it comes with like 10 different things including cloning gel, and it gives you a fair-sized container of Sugar Daddy which works better than molasses. Whichever nutrient company you go with, they provide you with a feeding schedule and stick to that.
Then you can add in other suppliments. I include the following suppliments with every feeding, and note there are suppliments out there that you buy just for flowering. I use Hydrozyme (which helps break down dead roots and build new roots), SuperThrive (you use a gallon a drop, said to be gold amongst the growers out here), MagiCal, SugarDaddy, and I'm trying out some others.
You force flowering by hanging a tarp over the crop. If you live near farm land, you'll notice that some farms tarp their fields during certain sunny parts of the year. It's the most common outdoor way I know of. You can get giant black plastic tarps in a roll at Home Depot for around $20/roll. Make sure it's light sealed, and if you can find a way to get a flow of fresh air whether a fan or some make-shift vent then that would be brownie points. You might need to make a frame out of 2x4s or something.
If you want to get something on a timer, I suggest buying disco ball spinners off ebay (absurd, I know). You can tie a thin rope from the corner of a tarp connected to the disco ball spinner, and when the timer goes off and activates the spinner, the rope coils itself and pulls the tarp up. You can have a separate line, spinner, and timer to pull the tarp back the other way.
Trust me, it took many smoked bowls to come up with that solution for my outdoor green house
