Welcome to RIU, and the wonderful world of cultivating the world's most misunderstood and feared medicines!!!
The only 'advice' I can give you or anyone is to read and learn and then apply what you have read and learned to your garden and you cannot fail. Anyways, remember the search tool is your friend...Lots of folks here willing to help a new farmer get up and growing. But at the end of the day your grow will be only as good as the knowledge and work you put into it.
It is always great to ask questions but do not take anyone's advice or opinions and follow blindly. Do your own research, you will be much happier knowing you have done it for yourself and by yourself. The first buzz you get from your own budz...is by far the BEST high you will ever have!

Good Luck and Great Growz!
Right now I'm at week 7 day 3 since light switch and everything was going fine and looking wild for it being my first time. So I went into my room when my lights kicked on at 9pm and everything was fine and lush green. I went back in the next night when the lights flipped on and all my fan leaves had turned brown and dried out and some left still had some slight purpling at the tips. This was not the type of yellowing you get in a flush either. I had no heat problems or anything like that. I pulled the plant out and flushed it immediately. It's been about four days and I thinks it's still getting worse. My setup is a 4'x4'x7' with a 1000watt HPS air cooled hood with a 6"x18" Phresh Carbon filter and a "8 Hyper fan sucking air out and pushing the heat under my floor dialed down to about 40%. I was using Fox Farms Dirty Dozen nutrients and Cal-Mag+. It's a soil grow.
