Curiosity killed the cat?

[QuixoticQuipper]

She is doing great, however over the past week she’s developed what appears to be a CalMag/ph fluctuation type of rusty mottled presentation on a few of the original leaves.
I sincerely appreciate any constructive feedback

You forgot to bring the patient

Pics are a major help in any diagnosis situation.

Not sure what happened with the pics sorry.

Pinch them / bin them ……. Monitor plant

DONE

Looks more like insect damage, maybe mites. I don't see any evidence of a Cal/Mag issue.

Any chance you spilled nutes on your leaves? I’ve had times where I was measuring near the tent, or topping off ppm of a res and made a little extra slash. Plant looks good, don’t let one or two funky leafs determine the health of the plant as whole.

Thank you.
Was my plan, however still building my toolbox and like to try and identify any irregularities if possible.

 

[QuixoticQuipper]

Thank you. I appreciate the feedback.

Cut back some on the nitrogen

Doesn't appear to be Cal/Mag issue. Maybe a phosphorous issue? Hopefully someone can help you.

Just went through a bit of this myself. My lower leafs were dark green/shiny ... too much N. Which is antagonistic with K. I cut back on the N, and it stopped it in it's tracks. Too much N will block your K uptake, which is very important during flower. Many thanks to HotRod for helping me diagnose this. He's got the knowledge.

Update: The issue has progressed, albeit the buds are rocking on nicely it seems.
I haven’t used any veg nutes since pre flower so not sure what’s going on with the nitrogen. That said however, it appears for all intents and purposes to be nitrogen toxicity. See clawing, dark green, and mottled necrotic leaves.
Note: I’ve been feeding a 00 Seeds White Widow auto alongside the Pineapple Express (is 1 week behind) the same feeding schedule and dose, and it appears to have less of a presentation. Pics included.

True. Cheers for the input
