Are you over-watering?
I heard with coco you are supposed to treat it like a hydroponic system and water it as often as possible. I am only watering once a day and water just to the point of runoff. Is this not correct?
In all my growing years I've never once seen a marijuana plant that was not rootbound in a container. cup, gallon, 10 gallon, and even a 35 gallon garbage can grow, roots were hanging out the bottom, twisted around and around, like, where are they supposed to go anyways? Eventually ALL container pots will be root bound in veg aye, regardless of container size.
Yes, what the Reefersaurus said
actually if you use air pots or something similar your plants will NOT be root bound and will not form big circling roots but fine roots filling the entire pot. They are used by greenhouses for long term keeping of bushes and trees.
I don't like growing without them, less medium use, can use smaller containers, added humidity a plus in winter and dry climes. Yeh, UB had a post years ago about the copper paint.
