Nährstoffmangel oder Hitzestress?

Hello Growmies!
Today I discovered some weird-looking spots on one plant thanks to the new light, which none of the others show under the same conditions. Is this a sign of heat stress or nutrient deficiency?

Nothing wrong, just a slight bit of damage, most likely from hitting the soil at night time when the leaves are lowered.
No need to do anything, it is not a nutrient issue and not a lighting or heat issue either.
