yeah, i also second guessed my calcium diagnosis cus theyre are too round… but maybe its just starting.
regarding the way to control mites… fuck. i mean abamectin is organic strictly speaking but if youre outside its not really an option… and pyrethrins (def organic) will prob not be an option either if youre outside. those two have been my go-to for both prevention and attack, but im inside and can control it not spreading to wild animals.
this thread/solution gained a lot of traction and followers among the organic crowd - never tried it tho.
