I'm using fox farm line of nutes, I'm into 12/12 for about 2 weeks give or take 2 days. some of my leaves on both plants have some yellow spots on them, some have just spots, others look as if the leaf its self is slowly turning yellow. the plant is VERY perky and looks to be very healthy. I've never done a flush on them. there about 4ft tall (aculty about 6ft but there super cropped with some LST also.) are these nute burn spots? or is this just from the plant flowering and slowly finishing its life cycle? or a combination of both? also could high temps cause this issue too? I'll try and post pics but I gotta find another light cause im using a HPS and that sucks for pictures. this started after I got in to floweing and I started using the big bloom plant food added to the other 2 FF products. thanks in advance.
