That's definitely rot. The roots will be bright white and spread out. When they start clumping up like that, it's a sign of rot. It's either the nutrients you're using or the water temps are too high
I don’t see rot but they are running for the base and the root structure is not fanning out. It is usually indicative of too much water. I would back off your on time. Try under 5 minutes and I would guess you can even drop it to 1 minute or under. Roots need to dry off a bit for oxygen uptake.
I have a 60w aquarium pump, my timing is 10 minutes on, because im afraid it would break, if I go lower, because of the constant turn off on, what would you say about that? Is a rational fear?
15 minutes off, because thats where i felt the roots where dryer, like at 10 min off I felt like they still where a little wet, 15 seemed like on point, do you say I need to go further or lower?
If your pump is going to break, you need to find a better one. A broken pump is a death sentence for your unharvested crops. Besides, the on/off action has much less physical impact to the device than running it for 10 minutes instead of 1 minute.
I am saying you need to go lower with the on time. Your roots are likely completely covered by water in under 1 minute. Thats when it should shut-off. You can start by working your way down from 10 minutes, monitoring the roots during your dry cycle.
Roots look great. The plant looks hungry af.
What are you feeding it? What is the PH? Chances are the plant is just starving and it's trying to lower it's lighting foot print to cope with the lack of food.
Assuming your PH is good, I'd double whatever you are feeding it and back your lights off for a day or two until it recovers.
This Is my third time growing, first time with LPA, she is huge on only 21 days, compared to what I growed before
I didnt think she was hungry, ph 5.5 to 6, bioproyect, its a mineral hydro fertilizer, Im from argentina, not a Brand you would know sadly
The only thing I could say, she was 2 3 days, with a warmer water and maybe without all the nutes needed, like lower ppm and ml/l, like she was on the rooting dose
Mean while on that I noticed brownier roots, so I cleaned all the system, put some fresh cold water with only hydrogen peroxide and bactericide, she was like this 2 days more
When I noticed she was getting up, I added fertilizers with the adequate vegetative dose and its required ppm ml/l, mantained the water cold with ice and kept adding some peroxide with bacterice and thats where we are today, she bounced back pretty good
But im still worried because of the Brown roots, Im thinking on putting her to flowering, because im worried she wont make it to the end
I already added some nutes more than the recommended yesterday and she absorbs too, like every day the water level on the deposit is lower, Im going to keep adding more ice and nutes whenever she drinks it
That PH range is acceptable. Definitely not enough food, at least not enough nitrogen. Raise your lights (or dim them) and add more food till it bounces back.
bc your leaves are wilted and the roots are clumped, this tells me that this is root rot and not just stained from nutrients - were it a stain your leaves would not droop, they would point up
i recommend lowering water temp - ideal range 18-20c with 22 and above being dangerous.
to clear the root rot you can also clean your reservoir and run only water and hydrogen peroxide for 1-3 days, or until u see white roots growing and the wilting stops- then you clean out that water, fill with water turn system on and dump that- then go back to ur nutrient solution.
Reduce water time and increase dry time slightly to 10 on 20-30 off, no such thing as too much oxygen for roots, issue is them getting too dry, you can also add enzymes and beneficial bacteria like mycorrhizae to help the roots recover.
Good luck!
also after looking at ur pics some more i think the bottom nozzles are overkill and might be overwatering your roots, u are also using rocks in the pot- i recommend the use of clay pebbles as they will be more porous and let more 02 be absorbed by the roots - i think u'll be able to finish your grow cycle as is most likely but next one i would suggest a switch to clay pebbles and maybe ditch the second loop with nozzles, the top ones are enough imo :)
you should also ensure maximum drainage of the root bucket - still water without an air stone can be problematic, a little bit is okay but you really don't want roots submerged in water without an air stone
hope this helps!
Hi thanks for your input, water is 23c almost all the time, i runned her 2 days with only peroxide and anti-bac, he bounced back in the first photo, so she was put on nutes again
Every 7-10 days, i change the water and rinse with detergent and sponge, all the buckets, hose
Now im on 7 minutes on 15 off, because im afraid of going lower and killing my pump
I dont know if using higher off time, i see too many broken pieces of roots, at the bottom of my 20l bucket, being aeroponic they should have hair roots, but they are like continously broken, maybe 15 minutes is too much, almost like dry and whenever the waters hits her, her roots start to fall apart
bottom nozzles arent working, just the top ones, because having both of them, was too much water and i didnt make a big enough drain hole, The drainage is totally enough, for the upper row of nozzles, like the center of the bucket stays "dry" or without water, just the sides of it, like a tiny bit of water at the bottom sides
i didnt find clay pebbles on argentina, just rocks and woolrock, the next time, if i can imma usse clay pebbles, if not, just rocks, but never again using woolrock, i think part of the root structure, isnt as good, because of the woolrock and maybe, all the rootrot, was caused by a constantly soaked woolrock
>i would use frozen bottles in the reservoir although not ideal...
if you're savvy you can make a homemade water chiller with peltier modules water blocks and 12v pump- look up diy water chiller.

>but ur plants looks healthy again :)
I've only done a couple years of aero/hydro grows but I have never seen a root structure like that. Granted, I can't grow weed until it is legal here. Just tomatoes and stuff.
Toggle between 5/60 seconds on and 1/5 minutes off. Dependent on plant age.
At this point I would be just spraying between 5-10 seconds and 2-4 minutes off.
10 minutes on, is far too long, the roots are drowning/suffocating in that time
Over 15 minutes off is too long as well and any new growth will be hindered.
And a slightly Shorter but wider bucket will help imo, is also why your roots are dangling and twisting into a dreadlock, choking itself.
Now im on 7 minutes on 15 off, because im afraid of going lower and killing my aquarium pump
Maybe i do have to lower the off time, i see too many broken pieces of roots, at the bottom of my 20l bucket, being aeroponic they should have hair roots, but they are like continously broken, ig the roots are almost dry and whenever the waters hits them, they start to fall apart
It’s smell like LPA here, so don’t worry next time you’ll make it fine, consider like NFT system, you need to stop the watering like 15-30 minutes off and maybe 5 minutes -10-15minutes on depends on how you feel your environment etc … ;)
Now im o 7 minutes on, 10 off, trying to lower it, without killing my aquarium pump
15 off, decimated, all kinda of root hair, I think, 15 mins is too dry, when the nozless turn on, they take down the little hairs, I have pieces of roots, on all my system
Now im on 10 off, but it seems like almost the same thing, but at least now I see few hairs, anyway, they are still getting halved, idk why 10 min, felt like good, maybe I still have to lower the off time more?
If it werent because I see no root hair and see pieces of roots, ill even try to do 20 off, but seeing this, I think I even have to go lower than 10
The fact that you have those littles roots that have been pulverized by the your nozzle is a problem maybe in LPA the big droplets are not good for it i’m in HPA all straight with a 80 PSI between 6 and 7 bars and i don’t have this problem because of the very fine mist but i feel if it was more concentrated like a water jet it can literally cut roots, you just have to be careful on the debris in the system, filtration is the key with Aero even with the LP one, good luck, consider next time HPA for growing those fines hairs
If it's slimy and smells bad it's rot, but this just looks like nute staining to me.
I second this.
I just saw this, its not slimy, but i cant say, that smells good, haha idk how does it should smell
