Young Plant Issues

So my plant is about a week old and its been starting to show dark coloring (Brownish purple) around the edges of its first two leaves, the leaves look kind of like they are curling upwards. Its been under florescent lighting and I have been feeding it regular miracle gro once a week. I think it may be a nitrogen toxicity but I'm not too sure since its my first time growing. Will post pics, but they aren't very helpful because my camera is shit. My girlfriend came by today and said the plant looked a lot bigger than it did yesterday so I don't think its growth is being stunted as the next set of leaves is coming in nicely, although they look a bit yellow around the veins as you can see. Also from the very beginning when it was sprouted one of the two splits (not sure what they are don't think they are leaves but its whats the first sprout from the seed) looks as if it has been damaged I think i may have burned it or touched/stressed it out a little when i was planting because i wasn't being very careful but it grew faster than I had been expecting! I think its a sour diesel plant as well. Thanks for any help/feedback https://www.rollitup.org/images/smilies/weed.gif PICS: Oh yeah and a few spiders have taken a liking to my plant as you can see, I figured they are more beneficial than harmful but not too sure http://postimage.org/image/9braghrvd/ http://postimage.org/image/6szo3negh/ http://postimage.org/image/k8xztepf7/ http://postimage.org/image/wfdxmib93/ http://postimage.org/image/5lx1bqqsz/

i could be wrong but a plant that age doesnt need any nutes. miracle grow is bad news anyways.

Do you think i should flush it out? I was told by some friends who grow and some online sources that miracle grow is perfect for any plant. I've also been told that plants need UV light to grow but that is total bullshit.
I didn't think a plant as young as mine needed any nutrients either but was told otherwise so i did it. Any more feedback will be greatly appreciated.

again, i could be wrong, but i dont think you should flush (unless the problem gets dire.. they arent in bad shape yet) because miracle grow is time released (maybe thats just the soil?) and the more water you give it the more it will release. either way, id cool it on any nutes. you shouldnt have to give a seedling any nutes until the 3rd or 4th node.

if you really felt the need to flush youd honestly probably be better off transplanting into fresh soil. your seedling is small enough that there isnt really anything of a root ball so all that dirt would (in theory) fall right off leaving the little bit of root that has grown. Not something i recommend though.

maybe someone else with more experience could chime in.

well thanks for the advice I'm definitely not going to use anymore nutrients in the next week.

anyone else think they know whats up or is it just that i was too eager to water with nutrients?
