What's the issue?

Hey. Some leaves have started to get brown and crispy and the whole plant seems a little like a willow to me. What do you think the issue is? Underwatering?
I grow in soil, it is an autoflower, from time to time I feed it an organic fertilizer, maybe once every 10 days, so not much.

I see your using the blumatt. Is that the only way your watering. I had to put 4 drippers on mine to feel comfortable on the watering. I had to water once a week even with the blumatt until I added the drippers

I just put them in a couple of days ago and am still testing as I am preparing for a vacation. I use two for that plant. I did not add additional water as I wanted to see how things would be while I am gone

Underfed and stuck in a corner.
