[![enter image description here](https://i.stack.imgur.com/2qETn.jpg)](https://i.stack.imgur.com/2qETn.jpg)I purchased this plant about a couple weeks ago and when purchasing I saw these strange tiny black spots underneath the leaves but I went ahead and purchased anyways since it was the last one left. 

Could someone please help me identify what these spots are? Thank you so much[![enter image description here](https://i.stack.imgur.com/T2cjC.jpg)](https://i.stack.imgur.com/T2cjC.jpg)
