First glance makes me think
leaf septoria but that usually doesn't appear until flower.

Because
Whats the PH?

[Kinghsx]

Ph6.5…….

[Rwise]

Is that the run off, the in put or the soil?

[OldManGrower]

Looks like ph issues also add some cal-mag.

[Gingerbeard]

Why do the voices in my head ignore me and talk to other people?

[Farmbuck]

Why not !!

[GroBuddy]

With zero grow information dont expect much help. Or atleast accurate help. We're not there growing with you. Need to know what's happened up until this point. Many different factors takes a process of elimination.

Either hit the link at the top of this page called "Plant Problems" and look it up.
Or give us some info to go on, from the image my "guess" is PH issues or nutrient deficiencies (which can be caused by PH).
