i see its ffof soil and you added some perlite. ffof is a little hot for a yung plant, but the added perlite will help reduce concentration.
it may not matter by the next irrigation cycle, but if still a little droopy do water only and get a little extra runoff water - toss outside or down drain, don't let it sit in it. If it is due to hot soil, this will also reduce concentration a bit. i'd wait and see, as that just wastes what comes pre-amended in soil. i still think it'll perk up within a few days.
doing less is often more, if you can keep your patience. always tough to resist a knee-jerk reaction.
