I need help: yellowing dying leaves :pics included

well guys my plants seem to be dying off. I used fox farm big bloom on the blueberry and i fed my two pineapple express clones an all organic local made fertilizer. im not sure why all 3 are being effected. i normally just use bat guano and the poopoo goop and it all works out.

Maybe its a Ph thing? Or because i use the same container to mix the food for all the plants?!

bump no one has anything?

Christ Man ! THAT'S a drag ! I know it may sound stupid, but have you already done the obvious? Flushed 'em out ? Checked for "Spider-Mites" ? What we up here in the N.W. call "Root-Lock", when the plant(s) in question have been transplanted to a larger pot, without "Lightly Breaking Apart" the rootball, so it drains nicely,without removing the dirt from the ball ? Looks like it maybe a case of too much nitrogen ? So-So many variables that count, ya know ???
Best-Of-Luck my friend !
