looks like potassium. make sure your ph is in range and also check the ppm/ec of your runoff. my guess is to many nutrients caused the lockout

Brown rust spots on oldest leaves
Brown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?

Rust spots
My lower leaves are showing rust spots along the veins. Appears to be a magnesium deficiency but I am feeding cal/mag. I also growing in ocean forest soil. I’m starting to think this is nutrient lockout? I’m feeding a low dose of nutes(250 ppm every few days) soil could be hot?

Autos reacting to All-Mix: Slight nitrogen overload?
Pheno one showed very "leathery", weak, hanging leaves of dark green. Same time the fungus gnats had a run and the population doubled. After second LST also the stronger plant showed those signs on the younger upper leaves. Also curled down a little. Slight nitrogen toxicity?

Nute burn or pH Flux
Ive noticed the tips are the faintest of yellow. Maybe ive mistaken Nute Burn for pH Fluctuations? Diagnosing: pHing both tank and run off showed different ranges. My CYCO Coco pre-mix was ph buffered. The De-Gnat agent that goes over the coco for mite protection maybe causing.

Potassium Excess?
I feel like it looks like a Potassium excess, causing a CalMag deficiency. Any thoughts from the communitys? Old leaves are dark green with brown spots. New foliage is in light green (potassium excess) and developing brown spots on the new foliage as well (CalMag deficiency?)

Lockout? Can I remedy this late in the game?
I think this is more than a K deficiency. I think I'm getting lockout. And a lot of it. She's an auto-flower, and I grow hydroponically. Can I even remedy it at this point?
