Help needed

Hi guys,

Can you help me figure out what the issue is here? I thought it was a CalMag issue due to the soft water in my area, but after giving her about 1.5ml/L of the stuff, she's not improving. She's a few weeks into flower.

The leaves that are already like that won’t improve. Is the issue getting worse on other growth that looked fine before?

Yeah it's progressing to other parts that appeared OK yesterday.

let us see the full plant

medium?
light?
temps?

And ph

Sure thing...

Medium: I'm doing dwc
Light: 200w LED
Temps: 24degrees
RH: 55%
Nutes: AN pH Perfect base nutrients @ 50% strength
pH: Currently at 6.6 which should be OK with these nutes?

I change the rez every 7-10 days and top off with plain water inbetween.

Looks like root rot. Clean your rez and rinse the roots and they might recover.

Here's a photo of the roots

If u go on up to full strength on the AN it’ll probably bring that ph down some more and the uptake will improve

I'm running 50% as its an autoflower - do you think it would be able to handle full strength?

Yeah Looks like it needs it.
go 75% a few times then up from there. They get hungry as hell at this stage , actually before this stage so you can’t really catch up but you can hopefully keep it from worsening

Your roots look fine. A little more brown than I'm comfortable with, but it could be the lighting. Cannot say the I like those little white spots towards the base of your pot. How much air, are you blowing through the DWC? Sometimes the stones get all gunked up and it impedes the flow. It doesn't look like you have that problem. Just something that I would check.
The leaves look pretty dark green. That could be the lighting too. I've had that when I had too much nitrogen in the soup, during bloom.
The only thing I would suggest is bring that PH down to 6.2 and see if that makes a difference.
