At 491 PPM? It's nute burn. A seedling in soil should not be given any kind of nutrient, only calmag if your water is too soft, but never beyond 200 to 250 PPMs

With hot i think he means it has too many nutrients, not heat, but yeah, basically what he said, when you water give plenty of water, see if you can take some of those down, water untill a good ammout of run off has come out.
