Deficiency or nute burn?

well something’s different this run. What did you change?
You haven’t provided info on the nutes yet? The res temps are 18c and the room is 25c, right? You’re injecting air into the solution, how are you cooling it?
Tell us about the lights.

i missed that he/she is running full blast CO2.

i'd stop that until you get her healthy again

Nutes are no known for you as I live in south america and it is a local brand.
Water fluctuates between 18 and 22c.
Cooling with chiller

Then give us something on the nutes. It must list the ingredients on the label, copy them out for us here.
Lights??

Thats true, but some deficiencies also show tip burn

Those pics kind of look like your plant, especially the last one.
No I’m seeing .36 % zinc in your pics, so that’s not likely.
There’s a lot of NPK in it, I can see how it’d be easy to burn a plant with it. If you only got up to 330 ppm (.66ec) on 130 ppm water, it’s only 200 ppm (.4ec) of nutes in solution. I have to agree with you that it’s a little light to burn up your plant.

Look at roots, I think this is the culprit. And it seems to get worse where root touches the water, any new root that pops out turns to brown quickly.
Water has 1-3 ppm free chlorine (measure by chlorine test)
Any suggestion?
Tap water is 130 ppm, im thinking of buying distilled water and trying new nutrients

I don’t see anything wrong with your roots. A little staining is normal. They don’t look slimy in the pics, do they look slimy to you? Smell them, they should smell good, kinda fresh.
Your 130 ppm water might not be a bad thing. Mine is 55 ppm and I’m getting some pretty good ph swings on powdered nutes (Jack’s 321). Next to no carbonates in my water. Your’s is on the high end for hydro BUT it might be full of carbonates and calcium.
How often do you change out your reservoir? If it’s often then I doubt you need the chlorine at all.
You’ve got a few things going on here, maybe it’d be best to simplify things a bit. I don’t want to fuck up your plants but here‘s what I’d do. Dump and mix a new tank. I’d take @tehdansauce ’s advice and cut that P number. Can you drop the B part of the nutes so you get closer to the ratio he mentioned. I’d skip the chlorine and h2o2 for this tank.
I think all you have is an issue with nutes. If you have another line that you’ve used before or want to try out this might be a good time.

I would suggest phosphorus excess, in my studies and research npk should be closer to 2:1:3 or 1:1:2. If A and B are the same amount adds it would be 39.5N:55P:47K. Making P the highest amount... which could/would cause numerous lockouts including zinc. Good luck, take care!

Took your advise, i renewed the solution.
30ml A, 10ml B, 30 ml D
320 ppm, ph at 6.

pray for me

You’ll be good, just watch them. Is your ph mostly stable or does it move around?

everything is stable as a big rock, havent seen any drift in pH since many weeks which is really bad as normally ph should increase
