Purple Kush feeding habits

Can anyone offer me any advice gained from experience in growing purple kush? Im especially curious as to what it's feeding characteristics are. Is it a heavy or a light feeder? Sensitive or durable?

Just picked up some cuts from a local club and they werent able to give me much info about growing them besides "ive never had much success with them." Also, any other advice when dealing with this strain is welcomed. Thanks!

i have 5 pk right now. I would say they can take a good amount of nutes, but i do not feed them any different than the other strains i have and have never burned any. They definitely grow slower though.
