Hey there,
Welcome to the site! I just finished my first grow and the people here helped me out a TON. Listen to suggestions, the folks here know what they are talking about. If you aren't doin it already, make sure to ph your water before feeding to 6.5 - 7, i had a bad lockup problem in my 3rd week of flowering because I had really alkaline water from my tap. Good luck with the grow!
