Welcome to RIU....Use the GrowFAQ and search functions and you will find alot of answers.
There are a few things like light times and bloom nutes etc...

Give us a little insight to your grow room,
lighting,
setup.
The people on this site are great and can help you with anything,
But we need to know where your coming from first.

There's no real such thing as essentials without a purpose,
if your trying to obtain massive buds like any sane man,
then you'll want the right nutes blasted at the right time.
Are you hydroponic?
Indoor soil?
HPS/CFL?

I'll help cha out.
