i say that it looks like its done to me remove some of those dying leaf. if u have new growth then its not time but if no new growth cut dry and enjoy!
slow release get em everytime. use mg org soil,1 tbls of mg bone meal,mix in soil. take them from seedling to flower with just water. then when about to flower give them a half strenght of a bloom fert.(fox farm big bloom+ ff micro nute )water 2x feed once and so on until 3rd week in flower then...
if it is one plant put it in a box poke some holes. when the land lord calls to say he or she is on there way put it in the car untill there gone. make sure to warm the car should be ok for a couple hours or untill they leave.
there is a nute that is locked out or lacking in your fert. dont worry almost everybody gets purp stems sometimes it goes away sometimes it doesnt wont hurt your plants at all.
i have known friends that have used hemp depot 2x without a problem, would use them myself if i wasn't such a coward! use blank money order takes longer but stealthy. g luck!
