One of my plants dying from bottom up

[Tuga94lx]

Hello, I have 3 northern light auto, and only one of them is getting yellow leave and dying, I had to rip of some leaves that dies completely already. I just gave them all a flush with ph 6,5 to see if it's nutrients problem. I have no idea what it could be, any help? 99% Most of the leaves that are dying are from the bottom. But all the branches up to the top are bending down like she is sad. Photos attached

Drowning roots? Hows the drainage in that bucket?

What do you mean by drainage? I made 4 holes in the bottom of the bucket if that's what you mean

If you stick a finger in the bottom, is the soil wet?

Just a guess but too much water and not enough oxygen dampens the roots so she has to feed off the fans nutrients.

So if problem is not enough oxygen on the roots, is that plant on the photo dead or can I solve the issue?? Cuz she is looking pretty sad and I just ripped off many yellow leaves....

Not dead, she’ll finish by cannibalizing the fan leaves. You can pull her out to check the roots, put fresh soil in the bottom. Thats about all i got for help. Maybe somebody else will say its a deficiency to chase.

It's now been like 2 or 3h since I flush them, the plant I was talking about, the brunches seem to be getting up again, I drilled a few more holes on the bottom, soil seemed dry on the bottom, I usually give them about half a liter of water every 2 or 3 days, but maybe I should increase watering

Thats good then, underwatering and overwatering look a lot alike.
