this is my first grow with autoflower and started the seed in a root riot cube in a plastic cup surrounded by coco, when the seedling was about an inch moved it over to its smart pot (didn't put in there first because I realized I didn't have enough coco for my 3gal smart pot) The plant hasn't grown at all in 6 days , still looks healthy, but still an inch tall. The seed is a blueberry kush, using a 600w led 18 in away, in a 3x3 tent. any ideas?
