i have no idea what im talking about but i fuigre ill try to point u in the right direction... ive herd that dots on the leave's might be caused by "spidermights" it would be the spot where they sucked the moisture out of the plant... or it might not be
but itll always better to be safe... so i would check the under side of ur leave's they should be easily detectable upon closer inspection ( little black dots moving and eggS) if this is the case imediatly look into spidermite's and u can begin with 2 things ive herd... either find something plant friendly that kills bugs or if its only a few leave's ive herd goin over them top and bottom with a wet sponge will get rid of the problem done repeated times.. something about turning the leave's upsidedown to hatch the egg's then sponge them idk... disregard this if it is not ur situation
