Immediately clean flush your aerogrow, or as the technical term I like to use....flip it.
I'm not going to tell you to switch to a different brand of nutrients because I don't know anything about Fox Farm's hydro nutes. I personally thought they only made soil! I use GH 3-part series, which has been around for years and I've used it successfully in many grows. It may not be the best in everyone's eyes, but its tough to find people that say it doesn't work at all. So its a safe bet in my book. Botanicare though...I've never used. To each their own..
So...that looks like a major Nitrogen deficiency. Which would make sense because plants in veg use a large amount of nitrogen in comparison to flowering. It sounds as though you gave them mostly flowering nutrients, which usually contain low amounts of nitrogen. So a nitrogen deficiency isn't all that surprising. That all said, you could be experiencing other issues as well...which is why Hobie was right in the first place, flip the system in the instances that you don't know what is wrong.
Lastly, but not least...I would suggest that you maybe get a book off Amazon or something. (my fav:
http://goo.gl/dosSn) Not trying to be a dick at all...(I've ordered now 4 marijuana horticulture books from them). I say this because it seems your plants are extremely in need of N and perhaps with a little education, you could have caught this earlier and given your ladies a better chance at survival. Hobie wished you good luck cuz your ladies are hurting bad! You would hope to see green at the new growth sites...but even that is dismal.
