Drooping tops on the girls

I have a plant that is into flower stage for 2.5 weeks. The tops are drooping. She is under an array of Compact Flourescents, with a fan continuously circulating (day & night). She is a special strain in a DWC hydo unit, using PPB, Hydroguard & SM90. Water is room temp (76%F) and is air pumped. Fan on lower leaves. Since she has gone into flower mode, her tops are starting to droop / curl under. PH is maintained at 5.6; She is flushed using Clearex 2 to 3 week intervals. This happened on her sister, lease help.
Thanks for any and all help.

4 thoughts, rootbound, too much Nitrogen, general overnute (doubtful...the rest of the plant looks terrific) or root rot/fungus/damage to roots.

my guess is something to do with your roots.

And after rereading ....I think so even more. 76 is a bit too warm for roots....70 is best imho.

I agree that the roots are the problem; too warm and in a dwc, the roots are always partially submerged; I have used ebb & flow but am trying something new.

Any suggestions on what I should do to correct; I am using SM90 and flushing them, periodically with Clearex. Thanks for the help; I greatly appreciate it.

I personally prefer Cannazym for roots but if they get bad I'd switch to H202 at 2 teaspons/gal every other day of the store bought 3% or the hydro type (35%) at 2 ml/gallon every other day.. You can't mix peroxide with a lot of the zyme products....but I think you can still use your SM 90...you might doublecheck that.

You need areation to your DWC to keep roots healthy....otherwise they will suffocate and drown. Do you have a photo of your setup and roots?

PS...I use DWC for my plants and they do well as long as the roots have enough room and the areation is good.

I really appreaciate your help. I have attached a pic of my DWC for you to comment on. Whatever suggestions you might have will help. I have opened the lid on the reservoir so you can see; it is normally left on.
THANKS AGAIN.

I think your roots need more space. See Weedhound's modified larger DWC that is correct for growing big ass trees. Otherwise, they look good.

I do love bigger :D

Appreciate the photo....looks like good areation from here. Do you have a pic of the roots themselves?

I am sorry for the late response, been out for a while. I will try and get a pic of the roots later today after I buy new camera. Can you please send me a pic or info of a good DWC system? I have had good luck with an Ebb & Flow system but I am looking for other methods that work well / hopefully better.
I really appreciate all your help; to everyone.:thumbsup:
