I got up early to check my plants because there had been some leaf curling and little rust colored spots. I should of stayed asleep because they look like crap. I studied the GrowFAQ and it looks like either a Mg deficiency or ph fluctuation or combination. Their water has always been 5.8 so even though I don't have a soil ph meter, I don't think that's it. I also moved my light up several inches. As far as the Mg, the GrowFAQ says give it 1/2 tblspn epsom salt/gal, but does that apply to coco? I'm thinking about just flushing the piss out of them, but I can't imagine that it's an overferting problem because I have only been giving .5 mL/L each of the A&B so far. Any help would be awesome, even if it's just to say, "quit worrying so much, newb." Just remember when you look at the pictures, the plants are actually green in color, the camera makes them yellow. It's only the spots that become rusty that get yellow first.
. Besides that, the only development is I folded down the sides of the bags because they were flapping all around. Next time I am going to use some sort of screen or gravel at the bottom of my pots/bags because I'm steadily losing coco out of the drain holes right now. Rookie mistake I'm sure. 
Could it be that I just haven't been giving them enough nutes? But then again I've seen some pictures that were labeled nute burn that look like what I've got. It's hard to get decent pictures with my phone but here are some more for your consideration.
