Ok so I am in week 5 of flowering. Most of the fan leaves of my tomato plant are dying is this normal? Well not dying but they look like they are slowly cannibalizing
What is the percentage? (What are you calling "most")
I usually get a few leaves dropping off, but not many.
Post this question and some pics of the plant in 'gardening(everything except cannabis)' section, you should get more answers.
