Little yellow spots on leaves - Not urgent

[donpepito]

Hi all!

I´m trying to train two mothers for cloning, and some little yellow spots started to appear on the lower leaves of one.

I´m not sure what the problem is, but I´m afraid that it could be a fungus (Septoria) that can get spread all over the place.

Thanks!

slight nute burn IMO: miss a few feeds and a flush with air temp water is a good idea

good luck
