Curled leaves on tomato seedlings

kameronth · April 25, 2016

I'm growing around 60 tomato plants. Most look great but a few have leaves curling on them. Utyonok and Glacier are the two that show it the most. The rest of my plants look good. Any ideas on the possible cause?

Grown in 68 degrees, T8 6500 lighting for 16 hours. I use a light fertilizer every 1 1/2 weeks on all plants.

physiologic leaf roll. not a disease, a sign of stress though usually from being dry.

They may have dried out some. I potted them up this weekend but they were curling before I did that.

The inward leaf roll is simply a characteristic of Utyonok. It's not sick or stressed.

Thanks! I didn't know that. Makes sense that both Utyonok plants are like this.
