Ok! this is my first grow and its not perfect, somewhere along the way i messed up. I dont believe its nute burn becuz i only used the nutes solution 3-4 times and when i stopped and only water every other day the leaves continued to turn yellow, brown and then it would crumble up. Someone here told me it might be root bound. I went and got some solution to basically clean the salts or whatever it was in there. Anyway here's some pix... I was wondering if it's time to be put in flower... what do u think?
