Hey Panic, the light green shading in between the veins looks like mag deficiency. The rust spots are normally a sign of calcium deficiency but those don't look exactly like what I have seen in the past. I would assume though, because Calcium normally shows up right after Mag that it could be the case. The foliar feeding should help a lot. It does look like you have a little nute burn on one of the tips but nothing bad. Keep an eye on her and if you see any more of those spots develop you may want to do another foliar. It isn't out of the ordinary for them to begin showing Ca deficiencies in bloom when they are packing on the weight. Best of luck brother!
