Las hojas de mis plantas se han curvado hacia abajo luego de haberla regado hace 3 días

The soil is still quite moist, I've seen insects like thrips and fungus gnats, I've used potassium soap and neem oil. I've turned off the humidifier, leaving 47% humidity at 28°C. I've also raised the reflector to about 70cm above the plant. What else can I do??
