Sudden wilt! HELP!!

[xsailbox]

I have 3 plants in flowering under a 400w HPS in 5" hydroton netpots in a dwc system with drippers.
Its the quickgrow system(quickgrowcanada.com)
it has a waterpump with drippers with constant flow and a airpump with airstone. drippers only on when lights are on. 12 hrs a day constant.
the resevoir is about 40L.
currently using supernatural superboost 2/ h202 as nutes and recently changed last week to supernatural gro bloom with h202
the rootsystem on #1 looks like its dying tannish so I pulled it away easily and tossed it. #2 the rootsystem looks great. white colored. #3 rootsystem was looking great, white growing now shows very slight tan colour
all the same strain

during the weekend I had left for a few days and came back #3 wilting severely.. #1 & #2 are fine. #1 is in the 6th week of flowering.
#2 & 3 is in week 4 of flowering. the only thing I can think of on the wilting plant is that I had bent 2 of the branches about 90deg because they were getting too close to the light and getting a lil burnt. I also sprayed them all with sprayngrow & bills perfect fertilizer around this point.

just last night I added some big bud and voodoo juice in hopes that it may help with recovery. I also had put in some h202 before though so did it pretty much make the voodoo juice worthless?

any idea what the problem can be? theres adequate drain from the netpots to the reservior. any chance of recovery??

I remember I had a similar problem in a past grow with a wilting plant... In those cases I think the rootsystem grew too big for the 5in netpot and the water from the drippers wasnt able to drain down to the reservoir. I had bent those plants also at the time..

We need alot more info about the grow to really get any kind of handle on why this is happening....
How are the room and res temps ?
Pictures of the plants AND root systems would help alot here.


Anyway xsailbox,
At this point, it sure sounds like root disease.
If so, I'd isolate all 3 plants and treat individually with h202 treatment trying to get rid of all the dead root tissue, then before putting the plants back into the system, I'd clean out the res and redo it with weak bloom ferts and h202.

But, you've had repeated troubles judging by what you said in your first post, and it WILL keep on happening until you find and fix the issues or problems your current system and or grow environment is having.

Off the top of my head, and from the info you've given so far...
Continuous drip water pump CAN cause alot of heat in the res, even more than an air pump thats sitting in direct hid light. Heat in the res is the most common cause of root system troubles, as it also contributes to poor dissolved oxygen in the res.

I'd be looking at ways to help keep these factors from causing heat in the res, such as remoting air pumps out of the room or at least away from light and in the shade, changing the drip pump to a short cycle every few hours instead of continuous.
Using reflective mylar or reflectex above the bucket/tub system to keep it out of the hid light helps bigtime to lower its temperature.

But...If the room is running too warm, you'll never get the dwc res temps under control without having some kind of res cooling device involved. The first step regarding temperatures is always lowering the room temps, remoting ballasts, remoting air pumps, air cooled hoods, air conditioning etc.

Also...
Constant drip dwc needs to keep the dripping away from the base of the main stem, which can be another cause of root system troubles so maybe redirect or bury the drippers so the top rocks around the stem stay drier.

hth

btw...You're sure throwing alot of products at the plants...sheeesh

I had a similar problem with a similar hydro setup. It was called EZGroHydro and it was a single plant setup but they sold up to 16 plant setups. Anyways my problem also occured during the flowering stage. The problem was that those tiny net pots were cramping the root system and the roots started to rot and my plant died. lesson learned. Give ur plants room to grow. 5" pots dont cut it. Those are more for seedlings then flowering cannabis. hope this helps.
