Yellowing bottom leaves and burnt tips

Hi folks. I have 5 Super Lemon Haze and 5 Critical Kush clones in my grow box. This is my first grow, day 12 in veg. The SLH is looking beautiful while the Bottom leaves of the CK are yellowing and the tips are a little burnt. Spent some time online and I can't tell if it's nute burn or nitrogen deficiency. The clones were transplanted from rock wool cubes to the pots in the pic with foxfarms ocean forest soil. They were all yellowing a bit at first but the SLH recovered and are doing a lot better than the CK. I have been very careful about over watering so I don't think that's it. Also I have not added any nutrients yet and won't until my next watering but I know the ocean forest has some shit in it already. Any thoughts?

Oh yeah

Oh yeah

I should probably mention that the front row is the SLH, back row is CK. The solo cup belongs to a friend

Need some better pics to see what's going on. Close ups of the damage and full plant shots. Everything's blurry if I zoom in on that pic.

Ocean Forest is pretty hot soil to begin with and cocoa kush is very sensitive. Much less tolerant of nutes than slh so will need a lighter feed. Don't give them any food yet until you know for sure your problem.

If you're using tap water make sure you ph it to 6.3-6.5 or its very easy to get deficiencies.
