Should I defoliate anymore at this point?

hey there, i agree with budeegrowers about the defoliation, it's too late now, will only shock the plant for nothing . your main problem is your NPK ratio. See how green and glossy your leafs are, that's from N excess. you want to cut out anything with N in it from now until the chop . It's a bit late to fix such a thing, but i hope this helps ! 🚀
