First grow ever! Auto

the plant has grown alot since last time I updated and I'm very happy with its progress but I have noticed some leaves getting browish spots on them. maybe I started the bloom nutrition too strong but we will see. the 8 ball is growing up very well too, that gets 1ml Coco A and 1 mil coco B. the kush will be put under a 50w 3000k cob when that's all sorted in a week or so. also I plan to grow it in veg for some extra time and add more cobs to get a big yeild. I hope!
