When leaf serrations are curled and tipped up like that it’s likely to be heat stress, overwatering/root problems or extreme humidity. These leaves are showing signs of heat stress without light stress(burning/spotting) so light might not be too close but don’t rule it out. plant doesn’t look overwatered either and your diary states a RH of 50% so that should be good. Your night temps are up to 23 degrees though which leads me to believe your day temps may be around 28 degrees or more which is to hot unless running C02. If possible increases air intake/extraction and increase air turbulence with another fan and raise or dim lights a little. Just need to manage their environment a little better but it can be difficult if budget doesn’t allow. Hope this helps. Good luck 😉
