Lower leaves had some discoloration this anything to be concerned about?
What does the rest of the plant look like?
What are you growing in? Lights? Nutes? Hard to tell from the leaf if it’s cal mag deficiency or spider mites. I hope it’s cal mag….
Bio All soil, LED light, Gaia green nutes. I haven’t noticed any spider mites.
In soil, it shouldn’t be cal mag. I’d scope the bottom of leaves good to be sure.
Need a full plant photo.
Nutrient deficiency. Make sure the pH isn’t too high or too low (between 6.0 and 7.0), and give her a drink of fertilizer. If you are fertilizing a lot you could try flushing it and then fertilizing straight after. Flushing will remove unused nutrients and then giving it a drink of fertilizer will prevent yellow leaves caused by lack of nutrients.
I grow in soil i’ve had cal-mag issues in the past they stopped when I started using cal-mag+ iron so it could be cal-mag but it’s also a lower leaf and some strains just shed lower leaves if there not getting adequate light usually they’ll just shrivel up and fall off but sometimes the drop without shriveling up the strawberry cough I’m growing does it
