If that’s just the bottoms, I wouldn’t worry—- looks like there might be soil on the underside of the leaves? Flip them and make sure you don’t have spider mites.

Nute Burn? Or something else?
I'm seeing a lot of yellowing and dead/curling leaves on my girls. I thought it was nute burn so my last 3 waterings were nute-free, CalMag Only and pH'd. It seems to be getting worse. Could this be something else? Any advice is greatly appreciated

Yellowing lower fan leaves, a few red stems; N/Mg deficiency or normal low leaf die-off?
Is this a Mg or N deficiency or are these leaves naturally dying off? Showing on only one of two plants so far. Appears only on lowest fan leaves. F20, 7L pots BioBizz AllMix and nutes (1mL/L Grow and 2mL/L Bloom). Temp/RH are good. Can't measure pH. Local soft tap water 7-8pH.

Having some discoloration on the fan leafs. From a quick Google it seems to be related to nitrogen deficiency. Would adding some coffee grounds or other organic matter quickly reverse this?

They say yellowing is normal, but this much?
Not sure what to do. First time with autos, and they're around 69 days old. Breeder says 60-70 days mature. Used living soil. The yellow has climbed both plants yet the trichs are only 15-20% amber. Will my girls be okay? What kind of TLC can I give them until harvest? Noob here
