Yo, did you ever figure out what was happening to the plants? I'm in the middle of choosing between my first grow light(will only be using one 2x2x4 tent with one plant, which brought me to your post: led vs hps vs mh. Got any suggestions? It can get hot in my bedroom and will be growing in a closet inside of a tent.Ok so a couple of my girls are looking a little under the weather and I'm open to anyone putting in there two cents on what it is and how I you would treat it. check out the attached pics
