Royal Jack Auto PC Case

Upgraded the PC case for its next grow whilst my Easy Bud is curing. Started the grow with a CFL this time. I'll switch to the LED after the plant becomes a little established. Its been a hot week so its been hard to keep temperatures down. But I've borrowed a humidifier and aimed it at the air intake, raising the humidity and therefore reducing the temps. The first leaves came out with yellow spots, not sure if it's water burn.
