First CFL Stealth Grow Auto Somango + Uknown Buddha seed

Hello everyone, after spending hours and hours of reading and learning on this awesome website I decided to give it a try and grow my own buds for my personal use.
Guys, your advise is the main point of this journal.

The setup:
2x2x3 Stealth Speaker box (I called it "Box of Happiness")
reflective pads (car shade material)
homemade pvc pipes light fixture with 10 cfls (1) 50w 2700k (1) 50w 6500K (4) 30w 2700K (4) 30w 6500K
Apollo Adjustable Rope Hanger
Galaxyhydro 180w Led UFO (for future use)
(1) 118 cfm pc fan exhaust (ill add carbon filter soon)
(1) 50 cfm pc fan intake
Hydrofarm Timer
Ambient Weather WS-07 Wireless Thermo-Hygrometer (so I can know whats going on without opening the box)
(2) 5 Gallon pots + 1 for Fast&Vast ill be adding tmw
5.5- 6 ph potting soil (the best option i found in my city)

Germination:
I used 2 methods to see whats better
1-Unknow strain from Buddha seeds pack - germinated in soil (I didnt like this method because of the stem bend and droppy leaves)
2-Auto Somango from Advanced Seeds - toilet paper method.
3- Fast&Vast still germinating in toilet paper.

Please checkout the photos and let me know what do you think.

Hey, looks very cute. And I think its still too early to think about dark spots. It looks healthy to me. Good luck with your box of happiness

Here is how they look now
