I have one that will stump the masters.... Huge props to anyone who can figure it out

I need to make this quick, so here are the basics....
Problem is in bloom room
lights--- dual spectrum of 1k hps hortilux with 600 mh alternating
aeroponics system in five gallon buckets... Roots never sit in still water... Drains back to main Rez immediately
medium---- none --- just root to air and water
nutes--- connoisseur base, cal/mag add for pump drainage
RO water--- running ph 5.6-6.0 variable
Each system runs out of same Rez delivering to 2 seperate rows of plants containing 7 buckets per row
same strain, all cuts from same mother.
i am only having problems with this one tank... All other systems and strains are problem free
Left side row health is proper, right side completely stunted and clawing badly..... I have been growing for over 20 years and in some of the most advanced manners known.... I have done work for advanced nutrients and SNS (Sierra Natural Sciences)
this has me completely stumped!!!
how can the same contained system, same strain, be healthy on one side and not the other.... It's all the same system?!?! Huge respect to the man or woman that can make sense of this....
I have attached images of the plants so you can see health on left side and right side difference....
Remember, before responding, these plants are the exact same strain in same system and problem is uniform from one row to the other.... Healthy left side.... Straight fucked on right side.....
Please do not respond to flex your knowledge of what can cause stunting and curling, I am aware of these causes, just can't for the life of me figure out why one side of the exact same strain is doing it while the other side isn't since they are all getting the exact same delivery of everything!!! Appreciate any and all help, and once again you have all my respect if you can figure this one out!

Been rackin my brain for a while and all i have is a question.

Does your rez fill out into the left side plants first, then turn and hit the right side?

I doubt it considering your history but if so the left side might be sucking out alot of the nutrients and by the time it gets to the right side its nute def or maybe causes the ph to fluctuate because it has less nutrients in the water.

Only a guess because ive seen systems run in that rectangle flow.

Best of luck to you.

Good question, but no.... Pump runs out and splits to both sides equally... Pressure may be slightly greater to one side or the other but nothing I myself have noticed and I check the flow pretty constantly to make sure heads are not clogged

Yeah i figured. HMMPH

The only other thing i can even think of that looks like that is being root bound but youre in hydro.

Maybe the roots are getting tangled and chocking each other out. You probably already use an enzyme so thats most likely not the problem.

Got me stumped.

Absolutely no chance of root bound.... I run complete open air.... No medium what so ever.... The roots have as much area as they could ever possibly want.... But I respect that you are thinking about it.... I know their is a lockout happening just don't for the life of me understand why only one side is effected.... Makes adjusting complicated to say the least.... Especially since the left side is perfect

Nitrogen toxicity right?

Super interested in what the pros have to say about this

Yeah i figured. Sorry im the only one posting.

Last thing i can think of would be P def or even N overdose.

Your leaves look the perfect color they just have the curl of heat stress or N def without as much of the yellowing. So maybe your excess N is causing the ph to drop so low that it makes P unavailable.

Whenever i switch to flowering i change the ph of my nute solution form 5.5-6 (veg) to 6.0-6.5 because P and K are more available in that area but nitrogen is still pretty accessible.

Last guess then ill sit back and let someone else try to figure it out.

Let me know if you do! haha

Roots are somehow in the water to long.

Definitely not an issue of over or under watering and roots never sit in water.... Only misted

Where are all the master growers, this site use to have a few

right side hoses got contaminated possibly?

thats what i was gonna say-


foreign entity in right bank supply line. hmmm......but from where? could it have an infection? have you broken the line for an internal look?

What have you done that's different? Have you made any mods/alterations or other changes to your setup?

Great thinking and I did consider that, but after cleaning as extensively as was just done and all lines being clear of blockage and the whole system being contained it just doesn't add up.... Algae does grow overtime anywhere where light and water mix up and since I do run through white pipes for my main lines I do get trace amounts of algae in the main lines..... But it was all thoroughly cleaned and won't build at this point with my intervals.... Only time it has a chance at all is when it sits stagnant awaiting a cleaning.... Quality thoughts again though, much respect! I couldn't completely rule out the possibility but I don't think that is it

I had 4 Buddha Tahoe and 2 of them looked exactly like yours. I reduced the feed amounts even, flushed too and they were like that to the very end. pH and ppm were the same on all of them too. Got rid of mom since it was a real pita growing. You try changing the amounts you feed? Just a thought. Curious as to what your problem turns out to be.

Just a newbie thought but are all of your bulbs the same brand and type? Could the light intensity be different on the right side causing the issue?
