help with some leaf spots

hy
im a first time grower and i notice that some of the leafs are presenting some strange spots. someone knows what they could be?
thanks

Check them for bugs with a loupe.

Looks more like you got something on the leaf that caused the spot than some sort of deficiency. Where are the spots on the plant? If they're near the bottom, where you water, I'd bet the culprit is just splashing a few drops of nutrients on accident while watering.

Cheers!
