They look great, really! Those spots are from light burn. I'd remove the burnt leaf and move the light further away a bit. Check again after 10 hoirs or longer. If you find a new leaf like that, move it a bit more. Only stop moving it away when you go for 24 hours without burn signs, that will be your ideal distance from the plants. Keep in mind, once the plants get taller, you'll have to reajust, so take note of that ideal distance for future adjustments.
The other leaves look like maybe heat stress, probably because of the warm light being close, and should improve as you get the right distance figured out. Do you have a thermometer in the room?
Good job, though. Other than that, they look awesome!
