I have an aero setup and my plants looked exactly the same as yours did when I first started I think I even have pictures up on the post (please help droopy plants near the top of the hydroponics page...jack and loc gave good advice the only thing I can think to add is not to go too low on the nutes...when I did I noticed the got kinda stiff in the drooped position...200 at that size is probably as low as you'd want to go cause there is no reason to add any extra stress to an already stressed plant...the leaves look just like in my grow they felt like lettuce before I flushed...but after I fixed the problem I didn't realize they were at too low a ppm to really show that they were all better...once I upped the nutes to 300ppm they jumped back within a day or 2

it takes a bit to get used to growin...the plants will definately bounce back like loc said...only problem I had was males and hermies because of the stress so if they are from seed thats' something to take into consideration as long as they come out female I doubt this will affect the yield much if any
