Hello ! The edge of your leaves is curling up so their is supposed to be a heat issue going on here but 26°C is the top of the temperatures sweet spot range (18°C to 26°C) so this should not be a big issue and your RH is a bit low but nothing that could really affect your grow as you will need to decrease RH at the begening of your stretch and flo. And as I can see your light is not too close and not too far from your plants. So I would say a slight overwatering is the cause , so prefer a bit less water more often than too much water less often. I hope it will help you 😁👍

To me its not under or over watering , Sometimes the different genetics the leaves just get really really big . This leads into the ends drooping a bit like I see in your photo's . Plants tend to make big leaves because they aren't absorbing enough light you will notice this a lot if you hike through the bush plants in more shaded area's tend to have much bigger leaves then the ones more exposed to the sun . To me I'd say your light is a little to far and your plants are just making leaves a little bigger so they can soak up the sun . You can fix this by simply lowering your light to 19.69 inches (50 cm) or lower if you can do so without risking light burns . This will make your new foliage that comes out not as big and a result may not droop . Another things that could do this is very very high humidity during the night time . From what I can see your humidity during the day is 60 % and I imagine it shoots up quite a bit at night . Try reducing these numbers to around 50 55 % during the day and no higher then 65% at night although young plants like high humidity's long periods of it can cause problems and show symptoms such as drooping leaves and even twisting and discolouration . Over all you're rocking and rolling and I wouldn't sweat things too much it's all an easy fix and you will be right back on track ! I hope this information helps you to understand how light works as well as humidity for prolonged periods . -Happy Growing!

Yes, you are not supposed to let your coco dry, that doesnt mean that you have to leave it soaping wet. Even though your pot is 5 gallon, when watering remember that the plant is still small, water accordingly, say a liter every 5 days, until the roots are better established and fill the pot. By the way, you might be over reacting, I dont think they look droopy.
