QUOTE=GrowerXLT]BlueBear,

Thanks for asking the above question. You pointed me in the right direction so I can finally start to understand why my plants are doing poorly. You rock brother.

Hey XLT, I am glad you have found a clue to your problem. It seems to me that at this point in the game you are so late into flowering that there isn't much you can do. I am going to do some snooping around and see if I can pick up any ideas though.
Perhaps washing off the roots in a peroxide salution may help, or adding a little peroxide to the res, 1tsp per.. I don't remember, need to search, also I am not sure if there are any negative affects with the nutes you are useing, what are they GH or advance? I know that the peroxide treatment can have a negative affect with organic nutes. Hope someone else can chime in as well.
I would also consider getting those roots out of that rockwool and placing them in grow rocks
or lava rocks as the mediam. At that point you can run the drippers 24-7 and perhaps your roots will respond a little better and might be able to produce some new growth.
New growth is going to be the key at this point. You need to get some cleaning salution for those roots, IE peroxide and then start looking for new root growth. Also, do you have any clones on stand by? Just something to think about.
PS. try to use the search tool and check out any related terms I mintioned above, I may or may not have time, but hopefully someone like Zandor can also check up on this thread, but I know that he is a busy fellow. Harddon, LW and GNome's help and any others help would be highly appreciated as well.
Adieu
