Dewgons first grow!

Whats up everyone? Most people call me dewgons, yeah I know its a pokemon. Long ass story from when I was younger. It just stuck with me. Pay no mind to it. Anyway, I'm new to this site and decided to join after reading a grow guide from the widow maker. I have always wanted to grow. Seemed like an exciting thing to do and I was always around flowers at a young age considering my mother was a florist. So instead of roses and tulips I chose to grow marijuana. I'm not sure how well my plants are doing so any type of advice or constructive criticism will be greatly appreciated

the attachments are from day 2 to day 12. I have 8 plants currently growing. On some of the plants my leaves are droopy. and others the leaves have brownish spots on them. I may be over watering them and giving them to many nutrients. I was gonna cut down. is this wise? I'm using 4 4' T8 Daylight fluorescent tubes. I just transplanted my children into bigger pots. I think I shocked them a tab bit. Here's a picture of my current set up

like I stated earlier any advice would be greatly appreciated. If you need me to go into further detail just let me know. Thank you I'll keep updating pics as they progress.
