Leaves turning yellow and crispy from the center out?

This is a friends plant. He thought it was the lights, so he raised them up, still no go. I'm thinking it's some sort of fungus. Any ideas?

You can see the progression in the two photos.

I don't know but check three factors ph off or to much water nutes or stress froml lighting or heat

Is his source water going through a water softener? Something is way off.

That plant looks like reveg. Kind of. Lots of small leaves. How old is it?

Sent from Northern Colorado.

And what size pot is it in?

im with u man u been given it windex

i droped a full bottle of a nutes on one of my plants and she dont look like that lol

NOT my plant.

Don't have any idea what he did to it. Already having him check the PH, I will post it soon. It's in 10 gal pot. It's about 3 months old now. I have not seen the plant in person.

The other plants he has are fine, it's just this one that is really... well bad.

In a 10 gallon pot it would be very easy to over water it. That reminds me of root rot or fungus gnats... or fungus gnats munching on root rot. What do you guys thinks? Let's assume he didn't pour windex in it.

Well he said he has not used any nutes on it at all. So, I'm thinking it's a big deficiency. I told him to call me with any questions, let me know if he needs help. He should have called a month ago.

BUT Root rot was the first thing that came to mind when I saw the picture. Thanks for all the help, I'm gonna say this one is a loss.
