Black spots on calamondin leaves.
I have noticed recently I keep seeing these black dots on my calamondin leaves I can scrape them off without much difficulty. Are they mold or a bug of some sort. Also the green stems of the calamondin seem to be a bit more brown in places I don't know if it is these things spreading I scraped them off and sprayed the leaves with hose to try drown and other pests I csnt see. Ive moved it away from other plants.
