[Relentless]

Alright.. only two ladies out of 12 that are doing this.. chemd and gorilla grape..42 days 12/12..
sorry for the crappy hps pics.. these two ladies are in the back of the closet..
can anyone tell what it is? maybe cal def?

def mag def.... more then likely you are locked out ph or just super salts... or you just are not feeding it enough mag.

my bet goes to ph is off in the pot... flush with water and check ph on runoff i bet your high or low...

well i would think ph but i give these girls the same treatments as others, and they are all perfect looking.. these are the only two out of 12.. im going to get calmag tomorow
