Needs advive fast!!!

I am using a home-made bubbleponics system with 9 plants.
4 are The purps and 5 are Blue sage.

The one girl i'm worried about started showing some slouching two days ago and now she's not doing good at all.

I first thought it was over-watering, but i was confused cuz its getting the same amount of food n water just like all the other plants.
so i removed the tube from the netpot so the only roots that were getting some food n water was the strand that hangs just into the water.
There are 9 air stones so the water is full of oxygen. and the strand that hangs into the water is even getting pumped by the airstone below.

But a day later and here I am. The plant is still alive but it isn't looking good at all. The signs of death increased while i slept. The bottom half of the plant is starting to feel a little dry. So I was like wtf how could it of been underwatering it? all the roots are getting what they need and no more. (well i thought) But yeah i put the tubing back in there so they are getting it again but i dono.

I did some research and saw that you can over food without enough oxygen getting to the roots. I have never had that happen to me before because I have air pumps on both sides of the water pumps. That is also why I removed the tubing from the netpot in the first place. Just because there were roots in the water getting tons of oxygen from the air pump below.





But yeah I am really confused of what's going on.
Maybe you can help me
Thanks

I would remove the sad one so it doest affect the others. The other 8 look good and you dont want them to do the same thing. It doesnt look like it will recover but you can try a seperate system for the one and flush it! Good Luck!

thanks but anyone else have any input?

is that opening on the upper left of tub always open so light can get in? what ph are you figuring? is the bottom of the rockwool cube on that plant wet? could any lights be getting to her roots? this is a root issue IMHO. did you try taking her out and letting roots air out for a couple hours to see if she perks?

also I see some magnesium deficiency developing on the two left plants.

no its not i just had it open for a bit.
and no i did not try to take her out an dletting the roots are out. I will tho right now.
n my ph right now i just checked and it is at 5.9
humidity is 50

I am actually going to be taking her out n putting her in her own little dwc with 1 airstone. gonna flush n hopefully she'll start to show some perks.

yeah and on the very right plant, u can see that half the leaf is very bright green while the other half is normal..

well you can foiliar feed with some epsom salts or simply add some to the resevoir. mg deficiency spreads fast. def. try lett her roots air out first.
and 5.9 is a little high IMHO-getting dangerously close to getting a nute lockout @ 6.00 ph and if you are not using a digital meter, and even if you are, there is always a margin of error so i would lower it a bit.

what do her roots look like compared to the others? when you touch her does she feel like she is drying out or is she still soft and lushy?
if she doesnt perk within an hour by letting her dry out than I would switch to watering her from the top with plain water. water the rockwool. if this causes her to perk up, than you have narrowed the problem.

please do repost and let us know what happens. My guess is if you top water her she will spring right back. this is a tricky one

yeah its weird though because all the nute problems ive had, iv had the plant showing signs of it. but this, just shows signs of overwatering/underwatering
she feels soft and lushy yeah, but the big shade leaves and the older leaves are feeling drier everytime i check it out..
do you suggest just watering from the top, with no water below whatsoever? meaning no air stone at all also?
orr?

n Thanks

yeah it seems to me she is starving fow water although dont know how possible that is being in a DWC. try some plain ph'd water from the top-dont think it matters if there is water below.
let me aks you a question. were these plants started in cubes and than moved to DWC? is her root length have the same vertical growth of the others and is the root growth significant or only a few?
