You may find your going to struggle with temps running a 600w and a 4 inch extraction in that space, I'd run your set up first before adding the plants, should give you a good idea what your environments like. Also your fans need to be running 24/7 bringing clean air in and taking the stale air out.
Start with the Rhizotonic first as you've mentioned 2ml per L every feed and depending on you back ground EC you may to add A and B from the start. your Ph needs to be 5.8 every feed as well. Which will be daily in coco once you have a decent rootball.
I keep my lights on temps around 25c and my lights off temps no lower than 20c with a humidity of 50-60% in Veg .
