Good afternoon growers. I really can't tell if I'm working myself up or catching something before it hits the other seedlings so anything helps.

Lights are FC-E 4800 x2 both set to 25% (lowest) at 18" above the canopy in a 5x6x7 custom tent that maintains ~68-72 degree range at 75-77% humidity.
This AK-47 seeding is starting to show what I think is light burn. The tips of the leaves are yellowing slightly and just barely starting to taco only on the very tips. This is also happening, while less severe right now, in my other AK-47 seedling.

The only thing that throws me off is this Big Bomb (as well as the rest of the seedlings) next to it show none of the signs the AK's have. This made me wonder if it could be strain specific? Maybe AK-47 is just less tolerant to the intensity of light it gets?

Here's the seedlings setup, AK-47's are both far left and Big Bomb is front middle. Mr. Mernch is on the right in his pot growing very nicely too, he needs no help.

It's got nothing to do with your lights. If anything seedlings like it warmer than where you are and your humidity might be a bit high. Other than that, keep calm and carry on
