welcome to the forum!
read through the
GROWFAQ and absorb as much info as you possibly can!
that is NOT a snide comment, it serious advice... it will not only help you get a clue on what to do, but also give you a basis for specific questions.
another bit of advice is develop a healthy dose of skepticism... there are a lot of well meaning people here who will steer you wrong on occasion for various non-malicious reasons. DONT believe everything you read!
case in point, i gave someone advice on clones going off of what works very well for me (and others) and it worked horribly for them... i know my method works for me and i certainly didnt try and fuck up their clones but that is what happened.
be patient and be smart with YOUR grow and do your homework.
take painfully accurate notes on your grows and you will become better with each and every grow. you will notice the master growers here (i am NOT one of them!) are constantly adapting their grows to make things better in their situation.
see what happens when you ask vague questions? some stoner comes along and babbles about all sorts of shit
