Leaves curling down and cupping
These plants are one month and 9 days old and the edges of the leaves are curling upwards cupping the leaf slightly. This has been happening for about 2 weeks and now on some of them the leaves are curling down. I am using organic soil that has a good drainage and i water about every other day when i see them get droopy and the top layer of the soil is dry. I am feeding them Pure Blend nutes and they are under a 400 watt mh with a bowl of water for humidity.
I thought that maybe the bowl of water had something to do with it but when I removed it for a week or so no progress was made so I put it back in. They are on a 24 hour light schedule too.
If anybody can help that would be awesome. This is my first grow and I don't want it to go to shit haha.
It looks like overwatering. Water them when the soil is dry enough to shrink a bit from the sides of the pot.

Its always backed away from the walls of the pot but I think It might be from me picking it up to water and the pot bending. About how ofter should I water them?

Plant Moisture Stress - Symptoms and Solutions
I have the same thing going but my tips are curling down someone told me it was too much nitrogen but I dont know if thats your problem but your serrations look the same as mine so it might be something to consider. I honestly think its a transpiration thing like moisture is leaving the leaves so the cells are becoming smaller on the surface causing it to cup.
Change your perspective, and change what you value, and you will change your boundaries.
