Tomatoe plant leaf curl
My plants in the greenhouse are showing signs of leaf curl. It started with one plant and seems to be moving to the rest over the last few days. Feeding/watering i believe is not the problem. I have noticed small worms in the soil approx 1/4 to 1/2" in length. They are white in color.
Please see attached photos. I don't know if you will be able to see the worms on the pink backgound.There is one below (2-3")the small lump of dirt on the left of picture
Any suggestions please on treatment.
