my first grow!

Well guys this shall be my first attempt at growing, i have a small cloning/seedling box i built, 2 125 watt cfl full spectrum bulbs, 2 23 watt 5500k daylight cfls, and im working on the closet that im going to be putting the HIDs in. i have 2 white widow X sweet tooth seedlings that have already started plus 4 more taprooted seedlings that have just been put in soil. i will be putting a 240/120v (better efficiency with the HIDs with 240 volts) set of outlets inside the closet and a vent system this weekend. im handy with tools, but i will need as much help from you regarding growing as you are willing to give. thanks guys and peace.

and here are my two babies. also, i have some herbs that im already growing in the small box, but it appears im having trouble, the plants have a brown discoloration on them, and my guess is heat stress. but you guys are smarter so any opinions?

sorry for the long break, i was working 88 miles from my house and had a few crazy weeks. but now i have four seedlings going, two at 4 weeks and two at 3 weeks. the two bigger ones appear to be indica dom. but we shall see since im a noobie.
