Yeah, it's heat stress. Increase the distance to the bulb. Now the last picture... are you sure you did not feed anything? Those spots look to me like nute burn. What kind of soil are you using? What about your water source?

Hi there! Yes this looks like a heat stress / light burn. You may have a weak phenotype. You should avoid any kind of spraying unless it's really necessary (nutrients lockout or bugs crawling around..). I also recommend to lower down your day&night temperatures and increase the distance between your plants and your light by just a few inches. I'll be around, good luck with these beauties!

Hi, Your last two photos definitely show signs of heat stress, try not to exceed 30 Degrees C 28 Degrees C is a nicer temperature and more ideal for them. Raise your light a few cms to around 60cm and that should keep it a slight bit cooler. Get a fan or two in there as well if you haven't already. Hope this helps
