Growing GHS Bubba Kush AND DP White Widow. DAY 20/16

Abbreviations or initials BK.1 = Bubba Kush "Green House Seeds" WW1 = *White Widow "Dutch passion Seeds" RQ.FS1 = *Fruit Spirit "Royal Queen Seeds" RQ.C1 = *Critical _ "Royal Queen seeds " I'm using the entire Advanced Nutrients line, EXCEPT Tarantula and Parana. What i really need help with right now is the feeding process, I know that the Root Riot has hormones or nutrients so i cant add to much. My Questions are as followed.. * When do i add VooDoo Juice and B52/ what strength? * When do I start the Grow Nutrients? * How should the environment be - Temp, Humidity, Light? * What do i do if they start yellowing? I started the first set of seed on the 16th and the second set on the 20th. I'm showing these videos for educational and HELP purposes. I have helped in other grows so i know the basics, Mainly the Bloom stage or the last 6-11 weeks. This time I'm all alone, and starting from SEEDS! so i would like some help from all you experienced growers I will be putting updates frequently so if you see this please keep up with me!!
