My first plant ever! Check it out ninjas!

This is my very first three week old plant . the strain im pretty sure is white widow. i grow it outside for as long as i can but i want it to have 18 hours of light so when it gets dark i put it inside under a cfl. my friend abandoned it cuz he thought it was dead but i brought it back to life with tlc and a shiv load of luck.what do you guys think? i put a quarter next to it for measurement purposes. Any tips,thoughts, or comments would be great!

Its a very lucky plant to have someone like you to bring it back to life. Good job. Hope its a female.

By the way the first set of leaves are the ones my friend sprouted and they havnt grown since but there still green , should i cut them off? and the tip of one of the bigger leaves got fried and is dead brown , should i cut that off? would it help? does it look stunted at all for three weeks?

Leave the green leaves on the plant. Cut off any brown areas.
