83 is getting kinda warm.
Is it my eyes, or do I see a few light yellow spots here and there?
How big is your box? about 2X2?
Try to get around 100w in there at least, and get your plants closer.
I vegged in a 2x2 with 98w, but when I flowered, I bumped it up to 305w.
Where's your fan?
Soil looks wet, and I don't see any Perlite.
