Do you have a diary for this grow? The only diary I could find has little information in it... Just judging from the pictures (not terribly good way to judge anything), it looks like you might have some insect issues (pic #1 & #4), definitely some nute issues (all the pics with dry, crispy leaves), maybe some overwatering issues (pic #3) ... you have a long comment on the germination week of your diary but nothing more... so I don't know how much of the nutes you're giving, you don't say how close your light is (that's NOT an issue here), don't know the temps, don't know the pH, don't know the humidity... So I just don't really know where to begin... telling you there's a problem with too much nitrogen, for example, isn't going to do much if I can't also give you a suggestion of what to do to alter that...
Bring your diary up-to-date and then re-ask your question... if you respond in a comment here on this thread, no one is alerted to the fact that you HAVE responded - it's not really a "chat" kind of thread...
Good luck
