DarkStar Coco Grow

Well I have officially hit my first pot hole on the road of learning Coco. I am by no means even a novice grower and this is my first run in Coco but I think I may have started giving nutes later than I should have and/or soaking the medium thoroughly and not raising the smart pot off the bottom of the tent to allow airflow to dry the bottom, which in hindsight is a pretty obvious mistake I made. The damage started off feeling and looking like wet toilet paper, the plant seems a lighter shade of green than I've seen before so I'm leaning towards hungry and water logged roots at the bottom of the pot. Feel free to leave some feedback on what you think it is. Live and learn, the grow continues!
