Wondering what this could be

Hello all

I’m about a week or so into veg on this autoflower. It’s inside In a tent under led strips. Anyone have any ideas as to what this could be? The leaves on certain spots are curling in. Heat stress or not enough water? I haven’t begun feeding them yet so it’s not nute burn. Is this the early stages of a deficiency? Again it’s under leds. Thanks for all advice and suggestions!!!

Also while on the topic...does this plant look healthy overall? Should I start feeding it or giving other supplements?

taco leaves! Heat stress. What your temp? Dont go over 85 humidity should be around 55-60

Ah no bueno! Temps today have been creeping in the low to mid 80’s today. Humidity is at 49%. The tents been moved to an upstairs room while a water heater gets replaced in the basement. Looks like it’ll be going back down to the basement tomorrow morning

I concur seems like heat/light stress. Check temp/humidity and measure light to plant distance
