Branch curling at top of tomato plant?
My tomato plants have been growing great, but now all of a sudden the new growth on each plant is exhibiting this behavior. The new growth is curling downwards to the point it begins curling under itself (some have referred to this as pigtailing?). It is not just the leafs but the entire branches and it is only on the new growth from the past week or so. Any idea what might be causing this?
FYI I am growing them in 3 gallon plastic pots and have basically been watering once or twice a week depending on the temperature outside. They have been getting about 4-5 hours of direct sun daily and have been under cover from rainfall.
Seeing as my plants look healthy, I assume it is just an environmental issue. What do you think?
