First time aerogarden cabinet grow PICS

Ok so I started my plants from seed about 3 weeks ago. I havn't had too many problems besides the fact that when I looked at them this mourning, they had wierd brown spots all over them. I stated to think it was nute burn, but I changed the water a few days ago and put 2 teaspoons fox farm grow big, and 1 drop superthrive in the gallon resevoir of my aerogarden delux. I am pretty sure this is the right amount to put in. Please critic me and tell me if I am doing anything wrong.

Those look really good man, are those clones or you started them from seed? looks like its gonna be fun, subscribed

Thanks man I have been doing a lot of research and didn't know if the aerogarden would work this well. Seems to be working, but I might add in some CFLS. They were mystery seeds that I got out of some buds a while ago, and all of them sprouted in 2 days
