My White Widow and Bubba Kush first pc grow journal

So after a long time of researching and waiting for the seeds I started my first grow on a pc box.
I build up the the grow box myself including:

Box: medium sized pc tower
Plants: 1 White widow and 1 Bubba Kush
Lights: 3X26w CFL (6500k for veg)
when I reach the flowering stage I will buy 2600k
I'm not sure about the lumens though.. is 1450LM a bulb is ok for the veg stage?
Fans: 2 medium pc fans
Temperature: 20-26C
Moisture: 39-57%

Please tell me if you think there's anything I can improve and how

Now let's move on to day 1 just after the seeds arrived :
I started to germinate 1 White widow seed on a paper towel and 1 Bubba Kush on a cup of water

Day 3:
White widow opend and has been planted
Bubba Kush didn't open yet

I put it on soil, with a plastic bag above, and watered it twice a day

Day 5:
White widow:

Bubba Kush didn't open and moved to a paper towel

Day 7:
Bubba Kush has been finally opened and planted

Day 9 (today):
The White Widow seems relatively small for one week from planting
What do you thing is the problem?

They're ok. Seeds grow up at different rates, just like kids. I had two og kush plants last run and one took off from birth, the other was slower but turned out to have a better pheno type which is why she's being reveged now. Happy growing!
