1st Timer.Need Help with a Few Things.(Nutes,Humidity,Co2)

whats up everyone.this is my first attempt. I am about a week from seed.I am growing skunk #1,kushage,sage,afghan kush ryders(auto),vertigo(auto),blue diesel(auto),red diesel,yumbolt 47,super lemon haze,power plant,afghan kush, and tangerine dream.
nutes:grow big, big bloom, tiger bloom,sledgehammer,microbe brew,and kangaroots hormex.
set up:2 8x7x6 tents one with 2 600 watt lights(both mh/hps bulbs),other has a 1000 watt light (both bulbs) both have a big carbon filter attached to air cooled reflectors,6 inch exhaust fan and both tents have mufflers on the fans. Also have an 8 bulb t5 for youngins.

when should i transplant these girls to light warrior? and can i use the hormex? will it help? and after transplanting to light warrior when should i start using nutes?i will be using miracle grow for this.should i use ocean forest instead? I already have the miracle grow along with perlite,vermiculite.
currently my rh is around 30%,temps 75-82 degrees.should the humidity be higher? should i buy a humidifier? and is co2 only used during flowering or can you use it throughout the entire grow? all replies are appreiciated.happy growing to all!

How can i fix this mold problem?
