i see a few problems for one you seedlings look like they where not very mature when the lights where flipped to flower. when you grow from seed it is a must (in my opinion) that you wait till the plant has alternating nodes or the plant will stretch out bad and there will be to much spacing between bud sites for those smaller nugs to come together to form massive colas. this is why i like flowering clones they are already mature i dont even flower seeds anymore they will be cloned and remain mothers or discarded and a clone will replace it for mother. another thing is light of course you have to think of it in grams per watt. a very experienced grower can achieve 1 gram per watt but if you are only running 100watts of light what can you really expect out of your grow. now t5,s are good floros as well as cfls but anything aside from that you are waysting time. HID (high intensity discharge) lighting is called that for a reason for the watts, you are getting much more lumen output than a regular old bulb would. get better lighting and start cloning and you will never want to stop growing.
