little seedling looks sick. I'm not sure if you can tell in the picture but the little leaves are kind of folding over. I'm using a topfeed/DWC hydroponic cab. I'm using a 180 watt UFO LED light that is running on a 20/4 light schedule. My pH level is staying pretty consistent at 6 and my PPM stays at around 61-65. although I added some nutrients so now its up to 91. the temp stays between 79 and 85F and my RH is at around 45. any advice or ideas?
