Are these being eaten or could it be the aircon?

[EarlyDayz]

Guys these are my seedlings that have recovered very well.
This morning one plant Pain Killer's leaves have curled? Chewed?
Couldn't find anything on the leaves themselves tho.
This plant sits at the front of the tent so when I run the aircon it could possibly be getting some colder air than the rest.
The other 3 plants in the tent are all fine and doing well.
Any ideas



2x 5 x 5 Tents, Coco Coir & Perlite
5 Gal Cloth Pots
HLG 600 RSPEC V2
Water PH Adjusted to 6+-
Veg: Professors Original A & B
Nulife AU60, Biodiesel CaMa+
Flower: Biodiesel Sensi Pro
Professors Flower Boost PK Enhancer
Natures Own Super Bloom
Steroid Bloom Stimulant

It may be stress from wind. The edge curling could be caused by mites like I'm battling and beating right now. A spritz with even plain water will help knock them off but if you've got Dr. Bronner's or Lost Coast Plant Therapy to mix in, it can't hurt. I've got hemp russet mites (or did) and I've never been able to see them. They wrecked several plants until I got hip to them. Google images of mite damage on cannabis and you'll get an idea of what my girls looked like. Whether this is it or not, the lesson I learned is that you have to work pest control into your routine or they'll attack and leave you guessing environment? Nutes? pH? EC? Lights? until you get it right.

Undergroundfarmer I've had mites and it looks different, mites spot the leaves this could be burn, will see tomorrow whether it is or I have to look at pest control. Thanks

Growell on the lights, I have two. My setup in the shed suffers through summer with heat (thats why I run the Aircon) and for some reason one light runs 5deg C hotter than the other.
This one is the cooler running one so it can sit lower, less power less heat same amount of light. At that height the plants at the edges turn in, not ideal. The centre of the tent is at 40,000lux while at the edges is 20,00lux In Australia these lights set me back $1400 each and honestly if I was doing it all over again I'd probably look at something with a larger footprint. So the LEDs are spread out more. Hope that's of some help.
