Maybe not a problem?

Lower leaves yellowing but also very shaded? Maybe cut them or am I looking at a nute problem? Will leaves turn yellow if they aren't getting light?

Still looks like mg def. The affected leaves will only get worse. They won't recover. You'll have to pull em eventually.

The OP's got some strange things happening with that plant. What're the plants being grown in?

Fox farm ocean forest and perlite

Leaves in the shade do eventually turn yellow. You can remove some which should provide more light if you choose to.

You made it,big thanks !!!

So you think I'm suffering N def too? She's getting a mix at 895ppm should I increase? I've already started boosting it by watering 895ppm then when dry I hit with 650ppm(last weeks leftover nutes) instead of distilled because I thought maybe a def.

Ok so I checked again today and she was dry but the leaves have gotten worse maybe nute burn? So I watered with distilled and if that stops the yellowing I'm going to lower my ppm back to 650 and try that here is the lower leaves I trimmed off but they are worse then before

thats over watering damage...you had over watered it sometime in the recent past

Ok I know for a fact it isn't over watered I wait until it starts to wilt and make sure its completely dry in at least 3 places with my moisture meter....

Ok def a problem....all lower fan leaves are getting brown spots and turning yellow, watered with distilled any ideas?

Looks like my plants from years ago when I watered with distilled and it was a cal mag problem since the water is distilled it is void of minerals. Hit them with a half dose of cal mag and see what happens. Old cal mag damage wont fix itself so you have to watch new growth. In my situation after adding cal mag I went right into nitrogen overdose since my plants were locked out due to the low cal mag so try cal mag by itself first before throwing any nutes at it.

I was doing a 1/4 dose should I up it?

UPDATE
purple kush 7 and 10 weeks old
You could see on the pictures what I give them when watering...400W
They grows fine but looks not that good...

Thanks!!!
