What could this be on my leaves?

GSCE autoflower day 12. This has been present for a week I would say but has gotten more pronounced. Light is viparspectra 900w

Soil is 707 formula with mix of nature’s living soil on the bottom 1/3. Topped off 2 inches of fox farms forest and ocean

Day temp 77 to 80
Night temp 65 to 72
RH 60 to 75 %

Any ideas or help would be greatly appreciated!

Are you PH’ing your water?

Yes it has been 6.3 to 6.7. I have another plant and it doesn’t have the same spots. @Nicky

Your heat may be a bit to high, max 78f
Also ensure your not overloading with light. It’s just a baby let it stretch a bit.
Also soil may be a bit nutrient rich
