Hey there, if they can be wiped off with a wet towel good. Otherwise I've had spots pop up from residual moisture drops setting on the leaves too long and being exposed to light...also if youre one who mists your plants be wary of water that hasn't had the chlorine evaporated out, if you choose bottled water any water "sourced from local, wells, or municipal water" it will most likely have chlorine and other byproducts.
Happy growing ✌️
