@CerealKilla don't be fooled in to potting up too soon in coco. I made the same mistakes. I noticed lots of roots popping out the bottom of the pot like a week after potting up and so I would pot up again but that's not necessary, not with coco. There's still plenty space for more root growth in the pot . Roots grow very fast in coco and the roots will reach the bottom long before the rest of the pot is filled out. When you think you should pot up don't and let the root ball fill out the whole pot. You don't even need to pot up much in coco, 3 to 4 stages max.
