Rusty spots, yellowing and really dark brown edges of leaf

[WestCountryGrower]

My leaves are looking good overall, but some have dark brown edges and some have rusty spots all over.
I put some photos in the thread... anyone?

Super soil medium
Green planet nutes
Nukens Strain
Recently started a kelp and cal mag to try and help this.
Just flipped 6 days ago

Thanks guys and gals

All the fan leaves look dead now sadly.

Looks like lock out check your labels for proper pH on the ferts you're using. Prolly to alkaline my guess.

Plants start using a lot of potassium in early flower. The yellowing can be the plant needs more nutrients so she grabs it from the fan leaves you just took off. So stop doing that.
Defoil is counter productive.

Think of those leaves as a nutrient sink of stored energy. Like a solar panel with battery backup.
You wouldn't throw out the battery bacause the panel was covered with snow right?

It's the 2000tsw
Couldn't afford the 3000tsw they call for the 4x4 so I bought a 5x5 tent and will be getting a second 2000tsw for my particular setup. Could do the 2000tsl but like the ideas of square
