Is this N deficiency, or is it something else?

Thanks for the help guys, I feel reassured.

I'm pretty sure that I know what's going on here, and as I've mentioned in a few other places I THINK this is just normal late flower N deficiency. But I wanted to fill out a trouble shooting form just in case it's something else that I can correct or avoid in the future. This is my first grow, so I just want to be sure. I flushed them each twice a couple of weeks ago, and then resumed feeding as normal after they dried out a bit. E-indoor or outdoor: indoor E-soil, soilless, coco, aero, Rating: 5

Well, i think that my theory about getting enough cal/mag by alternating my water has been proven incorrect. I'm reasonably sure that I've got some calcium deficiency going on. Brown orange spotting and generally crispiness. I picked up com cal/mag on Tuesday and watered with that. That topped plant is looking rough and not sowing signs of doing much, but the untopped one is looking better.
