Big Bang + Black Magic Kush + White Russian + OG Kush

This is my veg room separate from the flower room. I'm starting some black magic kush, white russian, and og kush. now i know the og kush is clone only but this batch of seeds where crossed with alaskan thunderfuck so i cant wait to see what pops out. There in the 2nd week from germination and i"m giving them 350ppm at around 6.0 ph all under a 400w MH, a 250w MH, and a 175w MH from right to left.
