Apologies, wasn’t aware autopots fed from the bottom.. salt layer at the top. Learn something new everyday.
I'd raise night temp as well, I believe its better to keep night temp closer to day temp.
A general comment... coco should only be flushed with weak nutrient solution, never straight water. RO and distilled are the worst, they leach cal and mag from coco.
A bit yes but it will take it fine canna handles cold ok its cold plus high humidity all the time thats the killer ime
Thats one of the downfalls of auto pots very easy to get salt build up with em im told vs some other systems

I just showed you what's it is. Your ph is off when you feed, and has been for so long you have your root zone ph out of wack. You have buffered your coco to a unusable ph. Stop saying random things and pay attention.

This plant is way to close to the light, in a room that's to cold, no humidity control only an ac in the room the tent is in.

What would you recommend to do then?

Something to consider. Root zone temp is important and I’m beginning to understand it more.
So when the lights come on they are at full power, unlike the sun which takes hours to get to full strength. Not to mention the ground is better at holding warmth than a small exposed pot.
This causes issues as the roots can’t access nutrients/water as easily and the leaves pay the price.
May not be the absolute factor in why the plant is unhealthy but will be causing stress.
19-21c is best for rootzone temp
This your ph is off bro its definitely that
No i mean when in bloom keep it low its not humidity that is the issue rn it is some nutes are locking out other ones long as the temps stay above 15 c that shouldnt happen but u over fed something and that can lock out other nutrients like magnesium as well regardless of temps thats what he talking about

So just I flushed from res or use a spray?
Best asking someone who uses auto pots that one probably from rez all the way to through the system id imagine bud

First thing to go is change how u measure ph. Your meter is trash or you aren't doing it at all. Figure out if your low or high. And water with the proper ph. Maybe a point or 2 lower or higher to start to swing the pH back. Say u want 6.2 in coco but your slurry test shows 5.0. your should water at 6.5 for a few waters because the coco is gonna drop that 6.5 quickly.till the pH comes back up
Better meter or calibrate
Slurry test
Water with proper solution
Don't flush coco ever with just water

I have a £600 blue lab ph controller and £60 ph stick the ph on both are same both are 5.9 ph i believe it’s 5.5-6.5 ph is good for coco hydro
