I am growing with a single 240W Blackstar, I have 2 diesel Ryders and 1 Trinity Kush. My growbox is made out of wood, lined with mylar, I have 5 gallon smartpots, I installed a shelf-rack for easier drainage. My temps are low 66.6 degrees and high 84 degrees, usually have average 78 degrees. Humidity is 30 to 50%. I have 2 muffin fans, 2 oscillating fans, and an Inline fan (TD-100X) hooked up to a carbon filter. My grow space is 22 inches long by 28 inches long and 42 inches high. Light distance from plants is 11" (don't know how close I can get with this led, can anyone please tell me how far I should put it from my babies?) I originally planted in Miracle grow and transplanted to 100% coco after i figured out that It was giving my babies nute burn or something. Im using coco and hand watering. Going to post some pics of the 3 in the transplanted coco. What does it look like I should do? nutes im using are SensiGrow A + B, SensiBloom A + B, Cal-MAG, and Big Bud Powder. [are these good nutes to use with coco?] if so, how much of each is appropriate? I water about 2x a day now because of the coco, people tell me I have to keep it moist all the time? correct? This is day 21 for my plants, Why arn't they growing bigger? What should I do to make them bigger? I've added 1/8 nutes yesterday once, don't know how much and when to re-nute them because they had issues with the miracle grow before, and still dont know if that was the only issue. All 3 of them under my Blackstar: http://i44.tinypic.com/2gwgp52.jpg Diesel Ryder #1: Normal CFL: http://i40.tinypic.com/2vxhhs8.jpg Blackstar: http://i40.tinypic.com/r6wbcn.jpg Diesel Ryder #2: Normal CFL: http://i43.tinypic.com/zv99c8.jpg Blackstar: http://i43.tinypic.com/ayokrt.jpg Trinity Kush: Normal CFL: http://i43.tinypic.com/4g5h5w.jpg Blackstar: http://i43.tinypic.com/2d0x306.jpg Please coco growers, help me out!
