DWC wilting sun leaves

Basement grow on a budget , Temps 70-75 with RH of 55%-60%
my 1st DWC garden , 5 gallon buckets w/air stones
600w HPS lamp 12-12 2nd week of flower .
FloraDuo @ 1100-1200ppm PH @ 5.8-6.0
Went into buckets 3-5-2012
3gal of H2O per bucket

The vein in the center of each leaf is very wide and almost translucent . leaves are sagging pics say it all Can anyone help ?
My girls and I have such a long ways to go !
I can take more pics if needed ! Thanks in advance to all who respond to my plite !

HELP ! Even worse this morning , now effecting tops !

Looks like some root issues, either bugs or pythium , how do the roots look?

Roots look awewsome nice sized root ball at 5 1/2 weeks , no spots that I can see all are the same color and seem healthy

If the roots look good then it may be a bit of N toxicity, dosent look exactly like it but sometimes symptoms do not present like would would think. You sure there are no larve or bugs in your water/roots?

You light looks kinda close, but it's not heat stress.....

How often do you change the water, what type of water (tap, RO, botteled)?

Is the water level in the buckets, above or below the bottom of your net pots?

How do the roots look? Like this?

I use hard well water @ 400 -550 ppm do a bucket change with min level nute once a week .
Water level 2 inches below net pot.
The light is the same distance as its been since they were tiny little clones , and moves up as they grow , and they all seem to still stretch towards it.

I havent changed anything except the light cycle @ 4 weeks . Started 10 days ago with one leaf
Maybe not enough of my root ball exposed ? I dont know what to do and dodnt want to start throwing a binch of changes at my girls and complicate the problem .
I did ad another air stone to each cuz I'm going crazy !

Maybe just back off the N a bit becuse you are right, those roots look fantastic. Also the addition of another airstone was a great idea. And good for you being patient and not doing anything to drastic. Give them a day to see if the additional airstone helps...by the way, WELCOME fellow 'Gander to RIU.....

The first thing I'd try is more bubbles.

Not gonna feel like a gardener if I loose this grow doubled the stones in each bucket 5 days ago still waiting for positive results but things just seem to get worse .
Growth has been massive till this issue . what about H2O levels and root ball exposure ?
The odd translucent color of the center vein I'v never seen before and wilting soon follows .

Leaves are pretty dark green and showing some wrinkles along with the drooping. Now if the drooping was a true claw like the blade in the very pic of this thread then I would say definitely N toxicity. Along with the additional airstones maybe a res change and refill with just water and no nutes for 3-5 days and see how they respond.....may not help but certainly could not hurt.....

edit: is there exposed water surface in the buckets? The O2 is exchanged at the surface when the bubbles break the surface, not as they travel up...maybe with those nice, healthy roots there is not enough exposed surface for proper O2 exchange???? Just a thought......

No Nutes is about the only other passive approach I havent tried .
* Reduced H2O Levels
Week later
* Reduced Nutes
5 days later
* added an extra air stone in each bucket
* today for shits and giggles and seems I'm running out of passive ideas I raised the light 2" .
* today will bucket change with Zero nutes . But sadly I dont think nute levels are an issue unless its lock out but I'm thinking I'm way to vigilent on PH levels ?

Here is another symptom I'v not seen before this grow - MASSIVE amounts of transference , so much that there is standing Moisture and condensation between touching leaves.(lots of air flow...almost dangerous amounts)
Just throwing as much out there as I can till something sticks .

Its not lockout or lockup. I am really wondering if enough bubbles are making it to the surface through that pretty rootball to properly oxygenate the water. Maybe mount an airstone just above the roots yet still a few inches in the water so you know your getting good O2 exchange.

I can try that ,
Bubbles amounts are massive now with 2 stones and 2 extra pumps .
Wondering about putting H2O levels back to where they were at veg (1" from the basket) running out of options feels like I'm running an obstacle coarse blind.
Might I be forced to continue guessing till death or harvest ? (however small it may be)
Any ideas for a more aggressive approach ?

You have massive bubble amounts but how many of those bubbles are making it to the surface and not getting trapped in the rootball? The bubbles must breech the surface in order for O2 to be absorbed into the water. Just bubbles passing through the roots wont cut it....

What about moving the air pump(s) ? I just realized you have them pretty close to the buckets, maybe you're pumping stale air.

Exactly what I was thinking when I saw the root ball swallowed the 1st stone lol
"massive bubbles" meaning what Im seeing making it to the top , many more bubles then before almost creating a foam (but not foamy if that makes any sence)
But was easy to mount one just under the H2O level as suggested

Moving the air pumps .
Lots of air movement and descent evacuation of exhaust and heat . But a passive aproach I have not tried thank you !
should have just enough hose to move them outside the room .
What about H2O levels being 2" below the net pot ? Is the level more importent then what part of the root structure is exposed ?
