Hi one plant has burned tips and get worse slowly. Its not nutrient burn. I suspect its excess potassium but would like someone elses opinion as this is my 2nd grow
The first 2 pics are bcn critical xxl auto and the second 2 pics are BlackBerry gum auto. They are getting the same nutrients the bcn critical seems to be putting up a hood fight against the disease compared to the blackberry.
Thanks in advance.
