It says you're using biobizz only and water.
Does this mean you're only using biobizz medium and no additional nutrients?
I don't think biobizz medium has enough nutrients in it for the full life of a plant, you will need to start supplementing with either bottled nutrients or something you can ammend in your grow medium.
If you're using Autopots, make sure to water from the top every once in awhile or the top of the pots will stay dry and will have root issues later.
