This week I am having the same problems, although they are coming around a bit. I have to get the watering problem solved before the next week, if I expect to see any decent size colas. The leaves and slowed grow were telling me they were having a hard time feeding. I thought the terrafibre was water logged so I slowed down the feeding to twice a day, without really much change. I decided to rip open the plastic surrounding the terrafibre and it was covered in mold. I have been treating the mold with apple cider vinegar but it keeps growing back. Lets hope I find a solution soon.
