Looks like he’s using auto pot system with cocoLooks like its not pulling up nutrients for some reason.
What style of grow is it? I couldn't tell. Hydro? Dwc? Rockwool? Coco?
Perlite I'm using iv always done it this way, and often do get roots in by my float and they always do just fine, I have always known tho that perlite absorbs water very well and after wonder if it is not the best way to do it, u was tough by a friend years ago to do it,I had a friend who ran these auto pot systems and he had a problem with the roots growing down into the actual feeding float. Idk if your having feeding issue specific to that (auto pot) (roots clogging it up). I can tell you 100% it’s not your VPD or your lights if there all the same kind. The other ones look healthy and way different then this plant. That plant specifically is infected or has something wrong with it and I wouldn’t be surprised if it’s something with the roots. You use Pearl light at the bottom of your pots? Or you use those grow stones like the attached picture for aeration? I think your supposed to use grow stones. Pearl light might actually differently and hold and soak up water creating a mold environment.
Agreed and ya my buddy did the same thing but he definatly used grow stones. If your pealite is just constantly sitting in a soaked environment like those auto pots are with the float then there could defiantly be some root rot causing this.Perlite I'm using iv always done it this way, and often do get roots in by my float and they always do just fine, I have always known tho that perlite absorbs water very well and after wonder if it is not the best way to do it, u was tough by a friend years ago to do it,
Ill try clay or blew next time I think
Could be root rot maybe and uptake sucks everything else seems spot on that i can tell
That should help a lot.I'm gonna disconnect the auto put tomorrow and hand water bottom feed till harvest that's about 3 weeks
Be interesting to see actually u can leave them dry a bit and see how they respond,
I'm going to tuen my water butt off now soon as if posted this :)
And see how they look to tomorrow afternoon after they suck the trays dry and bit more dry
It has nutrient lockout you have to flush it or it will get worseVideo below of a sick plant any ideas what causing it?
I have 8 plants I flower
5.5 weeks today
Last week or so hairs have been turning a little red
And
One plant had been getting really bad loads of red hairs and stems are turning red in the one plant really bad
Canna nutrients full line
Was on 2.0 E.c
That's tap water 0.2e.c I add calmag till my water reads 0.4
Then add canna nutrients
I mini flushes for 2 days and the 1 sick plant got worst
So today bumping it back up to 2.0e.c
I have 4 x 150 led q boards over them at 50cm away

^^^^THIS^^^^are the other plants the same genetic and pheno? If it’s the same pheno I doubt it’s your feeding or environment in general. The plant itself isn’t uptaking nutrients for whatever reason. To me it looks like there is an issue with the roots of that plant for whatever reason. Is this an auto pot system? It wouldn’t hurt to pull the pot out and look at the roots if there not white then they could have a disease. You can treat your rootzone for mildew and if your careful you can shake up the rootball and let the medium dry out if it’s just soaked and moldy with brown roots. If you use some azomite after looking at the roots it should the plant bounce back from any shock. Your a little late in flower to be stressin the plants out but it doesn’t look like that plants gonna get any better
