Few quick questions..

1. What kind of nutes are best for vegging and what kind is best for flowering? (What's the ratio of elements i need).

2. Should i top my plant? Can someone point me in the right direction of exactly how to do it as well?

The answer to all these questions are all in the forums. Try the growfaq first. It takes longer to type your questions than to get to the right thread from the home page. Not trying to be rude, but folks put alot of time and work into writing these faqs and guides. It is a waste not to read them. The more you know, the better the harvest.
