Can't help you without images. I also have seedlings in Sunshine Mix Advanced #4 and they are getting HUGE! They are just over their 1 week birthday. They are also under a 2' 4 lamp T5 and it's right down on them. They are loving it (you can see them in my journal). So any pics and we can try to help.
