Towards the end of those pics (the 11th one) it looks like you might have some sort of fungal issue going on, but it could just be the flash from the camera making it look powdery white. Also, those plants are really stretched out with some serious node spacing...how far away is your light? What kind of light are you using? Are you checking your ppm and ph? If you have a ppm meter you never have to worry about over/under feeding. Also, why did you decrease your nutes to 1/4 strength. If you are only one week into flowering your nutes should be going up, and up, and not coming down until you are ready to do your pre harvest flush.
frankenstein for sure dude. Don't take it the wrong way cause I lost my internet kid gloves long ago, but that fucker looks like hell. I would anticipate that you have a whole host of fucked up shit going on. But alas, we are here to help. I see signs of...piss poor lighting (huge internode spacing), micro nutrient issues (splotches on leaves), high heat or low humidity (curling leaves...crispy), and I would suspect that you have some kind of pest issue as well.. spider mites perhaps cause the plant just looks beat to shit.
So, we are going to have to take it all the way down to the basics. If you don't have a decent PH or PPM meter I'm not even going to bother but we need to know the following info:
feeding schedule
rez change out schedule
daytime highs, nightime lows, average humidity
PH range of nutrient solution, how often do you check...do you dilute your ph adjusters before adding them?
Ahhh, just saw the picture with your "grow lights". Get a proper HID set-up my friend. A 250 watt is all you need. I don't care what people say, CFL buds are a joke.
Get rid of the AN and buy your self a simple 3part nute while youre learning to grow.
FoxFarm, GH, something along those lines.
I put that on my sig because a lot of people who are new to this site (like I am) have no idea what rep is. All I kept getting was likes. And considering I am not new to growing, but I am just to the is forum, so it kinda sucks having to look like a noob when I'm not.Yeah I am total agreement with you on all points. First thing I thought of was the Holocaust and what the prisoners looked like. And begging for + Rep is for red headed step children look for validation. If you want + Rep give great advice consistently and it will come..

I've deleted it from my sig so that it won't offend the pretentious in the future.
You don't need to "flush" hydro..well DWC hydro anyways as there is no medium to actually "flush".
Changing nutes once a week is a very good plan. You can stretch the rez changes out longer in veg when the pants are smaller and uptaking nutes at lower volumes (thereby having less effect on the overall balance and concentrations of nutrients in solution...which is why you change the rez). ".
If I were you I would be adding 3ml of 39% h2o2 to that DWC setup every four days as well as I'm sure the water is not cold enough.
CFL's blow dick for growing.
