Magnesium?

[BCBudlady]

All plants grown in an organic supersoil concoction with a few extra bennies. Receiving GO Cal-Mag ph’d to 6.5 in RO water.
Grown under an Autocob. This is the only unhappy plant right now.
@Waira, should I consider some microblast and increasing the Cal-Mag?
This is GoldWidow CBD from the porta.
The other girl and boy are unaffected and hanging out in a separate love shack. Thanks for looking !

hey there BC'! ... you know, I have yet to get a solid reliable diagnosis of this specific symptom,... notice how the color stays (no yellow at all), irregular edges, and the tissue seems collapsed? It's not a defc. of any kind that I can call,.... Once, a old mate here had a plant that was left near a cold draft overnight, and next day had identical symptoms... some orchids at the nursery would do this too in really cold weather, and all I could find is a thing called mesophyll cell collapse,.... Earlier this year, a DP growmaster (AutoLowRyder) I consulted said if it's near or on the soil, likely it's an infection,... might have been in that case, but this looks well above the soil level? Sooo, you can see why it remains a mystery! ...it doesn't seem to spread much, if at all,... Nip the leaf off, maybe treat with an anti-fungal (if bacterial, it won't do a thing of course), watch and see,....

Thanks @Waira! I may have let the medium dry out a bit too much. Busy busy this T-Day craziness. Even the plants are stressed. Really need to reach the finish line on her, as it will be the only CBD flowers in the pipeline. Rest will be knocked up.
Off the shovel more than a foot of snow... with a little Cindy on board!
Thanks again, and I’ll treat with a little anti fungal.
