Northern Lights spots

My 2 weeks old NL are showing some spots on the oldest leaves, but they are spreading upwards to the 2 higher leaf set.

250 W HPS (250 cfl coming this week)
Temperature : 25-27 degrees celsius
Moisture between 33-50% (goes down when im sleeping)
Soil with vermiculite
water every 2-3 days with only water so far
24 hours light
They are inside a closet with good ventilation. Fan out, in and inside the closet

Have any ideas?

It looks like the area becomes dark before these "wounds" appear. And it looks like it spreading up the plant.

Maby i wil try to add some nutes, and even put it in a bigger pot.

The roots might have tapped into a 'hot' spot in the soil..(a nutrient rich patch) It should outgrow it. It happens once and a while, best way to avoid it is to start them in smaller containers...little 2"x2" starter pots.

Ok i will give it some days to see what happens. Best not to panic Thanks for the advice!

It also sorta looks like it could be pest damage. Hard to tell by the pics, but if you aren't sure, it's be a good idea to look around and see if you see any critters lurking.lol

where the picture ?? we cant tell by word we can tell by picture ..
