New Room new Grow

Week three is here and i finally found my digital camera!, So far so good here are some Platinum BuBBaa Kush , in a 4x4 ebb abb flow, with sugar peak nutes. i also have some lavender potted ,and a shrub of a Bubba Kush, little hectic.
Room is 6x10 with co2,can 75scrubber, 2x1000 blue hortilux halides. soon as this crop is off ,another 4x4 will slide on in!I am having trouble with the potted ones though , pale yellow, i figured a nute burn or overwatering, i flushed and ill wait, any input?
