Newbie at growing needs alittle help...

I resently went to Amsterdam and while I was there I bought some special kush (royal queen seeds) back. I'm only growing for personal use and I don't have a big set up, I'm not looking to get a massive amount from it. I have it in my closet where it is in a box covered in tinfoil with a strong light above it (not uv).
The plant is about 14/16 days old 6/7inches tall but only has 5 leafs and I'm worried that its getting to long and skinny. Does anyone have any advise about whats going on with my plant. Thanks.

Thanks for all the help (Y)

My first guess would me a light issue, what lights and how far are they from plant

It IS a light issue, first and foremost. plants tend to stretch and bend towards your light source if it isn't getting enough of it. there may be more going on here though: if possible, fill out the troubleshooting form!
