So I am attempting my first grow using the areo setup in the pics below. I have done everything I know how to do to get these girls (I hope) healthy, but nothing I am doing is working. Here is the lowdown: Medium= Hydroton and CocoTech 50/50, 5? net pots, areo sprayer system with a 15 gal res. Sprayers run for 2 hours every 12 hours (because of the CocoTech water retention), my ph is at 5.5-6.5, my ppm??s are at about 400, and I have them under a 400w MH in a Supersun CoolTube with fan.

Here is how it progressed: When I initially put the plants in the system after germing I was using about 40% strength of the recommended dosage of nutrients, Flora Nova Grow, with Diamond Nectar, Floralicious Grow, and Flora Shield.

I noticed the brown spots after about two days and tried to take action. I covered all my bases, such as, spraying them with a little neem oil spray, reducing the nute strength to 1/4th the recommended on GH website, (1/8th strength for the Flora Shield per the ??sticky? just recently posted here), and reducing the watering time to 2 hours every 12 hours (I was watering constantly before).

Is there anything I am not doing or doing to much of? What is causing my babies to die?

PLEASE HELP!!

BTW, I am growing Northern Lights, White Widdow, White Rhino, and AK-48, all from Nirvana.
