Why is ut curling?

[Binks420]

Hello,
I am currently growing a moby dick auto from pevgrow and the leaves are curling down. I have it under a 240 watt led for 20hours a day and water it every week or so with water until last week but i started adding some of the biobizz nutrients. Could anyone tell me what i’m doing wrong?

My guess would be underwatering. Once a week doesn't seem like enough to me, especially when I look at the top layer of your soil.

I thought that too but i put a finger in the dirt and it was still quite wet.

Water less volume. More often

They are drying out too much in between watering imo.

Edit: or the water isn't getting to all the roots.

Water to runoff.

When it needs it.
