I'll be calling UC Monday, but I'm dumbfounded at the speed which these girls took a turn for the death!
My environment:
50% humidity
77 - Air Temp
SOLID 67-68 water temp
PH in UC 5.8 right now, fluctuates up to 6.1
PH un feed rez: 5.8
PPM in UC: 440
PPM in feed res: 500
Nutes, Canna A+B (recently changed to bloom), Rhizotonic 1/2 strength, Cannazym 1/2 strentgh, SM-90, Zone 1/4 strength.
Basically they were fine and withing 12 hours drooped REALLY bad. We took one plant out a few days ago, she was the only one that did not recover from transplant shock (sunshine 4 --> UC). A couple days ago, another one took went from normal looking to droopy to yellow leaves with HARD stems in about 24 hours.
Decided to change some things about 12 hours ago and added a second air pump. My stock UC came with 2 pumps to be distributed throughout the system. A second AP-100 was added and now each AP-100 runs 7 buckets each. -- I was concerned from the beginning that I did not have enough air. Still not sure this is the issue, especially considering what some have done with the stock system.
The roots are white with no negative signs, kind of a PITA to get pics.
Less then 2 weeks into the flip. Blinked on 12/7.
Here was they look like now:
On this pic you can see the really sick plant in the middle to the left. You can also see the gaping whole in the net on the right side towards the center and again towards the rear where the two removed plants used to live.
Here you can see they are not all affected.
I'm dumb founded. There is not enough RO in our fill tank for a complete flush right now, so the nute rez will get filled with hose water, PH'd and then the UC will get emptied. The UC will then get filled with this PH'd hose water for an attempted flush.
Any other ideas? Why the sudden turn to death? I'm sooooo lost.
