I'm relatively new to growing, and just want confirmation from others that these spots are from a calcium deficiency. I also saw similar things online that can come from temp/hum, so I want an opinion from someone with more experience.
Yep I would mostly confirm that it´s a CalMag deficiency. I have/had one on my Strawberry Gorilla a few days ago and she got way better after adding more CalMag.
Check PH of your runoff water to be sure that your PH is alright.
Other than that I can only say you have some great ladies and I wish you the best for your grow.
For being quite new you are doing very well!
