My theory is you got behind on it's CalMag needs ... mine used to crap out at week 5 ... now I start w/ 2.5 ml/gal of Botanicare CalMag+ at about week 2 w/ each watering and about every 10 days I give it a double dose ... half way thru flowering I go w/ 5-10 ml/g w/ each watering ... some weed is supposed to start cannibalizing it's fan leaves at about week 7, perhaps that's it ...

was thinking that earlier cause my outside plants do much better gotta get that cal mag stuff
