What's wrong with this tomato plant?

Asalam alaykum Samira, the plant is currently indoors under artificial lights and the soil is dry. Last feeding was last week. It's potentially an iron issue but looks more like a potassium deficiency maybe?

Brandon I think if the heat inside is high, which makes the transpiration process large and thus these symptoms appear, air the place

Here is the entire plant with the lights off. Temperature inside never exceeds 74° F so it shouldn't be a heat issue. I've just watered in some CalMag to see if that might alleviate the issue, as well as a heavy dose of 6-4-4 liquid fertilizer.
