Hey guys I'm day 6 in my grow and noticed yestersay my Afghan kush ryder has purple in its leaf. Just wondering if its from my plant being in too hot of soil im using ffof and happy frog 50/50. Two 300 watt led vivosun blurples 24 inches above 2 plants in a 2x4x5 tent. Temps are 73-77. 90 percent of time is 75. Is it phosphorus deficiency this early? Too much nitrogen? lights too close? I'll post a picture from yesterday and today. Sorry not best pictures. And under lights But it is purple. Thanks
