Specks and burns?

[Millo]

Hey guys.
Noticed those issues over the past 4 days. Been getting worse day by day. Leaves yellowing and brown dots. What could it be?

Northern Lights auto 8 weeks from sprout
Biobizz Lightmix soil
Sf1000 qb @ 18in
55RH 80F
6.6 pH
800 ppm
( pH & ppm of nutes+water before giving it to the plant )
Watering every 4 days

@curious2garden could you help me out please?

Check under the leaves for spider mites?

Nothing alarming there.
Older leaves fading is normal.
Spots pop up from time to time.
It's not bugs.
Could be a small PH issue.

Thanks for reassuring. Do you think my pH is too high? I try to stay as close to 6.5 as possible

Your pH is fine. You are showing a little bit of a Ca def but not much. You have a little too much N on board, but nothing I'd worry about either. You could use more light but you can make it fine with what you have. All in all nice grow and nothing for you to worry about.
