1st Grow 250w(Closet) Bagseed and Sweet Tai

Hi all,
I decided to do a closet grow for the summer. Plan is to get a second rubber maid and stack it on top once the plants get bigger. I want to do LST once the plants get larger. I am using 1 Feliz 6500k 125w grow light (pictured, hanging from lid ), and 2 65w 2700 k(strapped down to the sides. I planted the bagseed into regular soil about 9 days ago, had some trouble in that soil which appears to have stunted it. The leaves turned black and one fell off, but she pulled through! Bagseed was moved to FFOF on tuesday. The sweet Tai was a freebie from attitude seed bank, germed and sprouted and is currently on day 3 from seed. I have the General Hydroponics Flora series (Micro,Grow, Bloom. Pics of the setup are attached, I put holes in each side (one large for the fan, and a smaller for exhaust.) Please give me feedback as to what I can do better, what should be changed etc. Thanks!

I have a few Questions:
-When should I start Nutes? How much per gallon should I add( I know this is searchable but i keep finding so many different answers)
-What do you make of the bagseed at day 9? how stunted is she?
-Are my lights in good position? (the 125w is hanging from the lid to about an inch above each cups rim, 65w about 2-3 inches to cups)

Update, the box got too hot and fried my bag seed plant... The sweet Tai is still alive but is definitely heat stressed. I moved the 125w cfl about 4 inches from the plant and turned the 65 w off. The seedlings leaves are pointing up around the edges and I can see some yellowing/browning at the tips. Am I correct to say that the plant has been stressed by the heat? Also, I filled up a spray bottle and was thinking about giving the seedling a spritz every now and again to keep it cool. Good idea or no?
