Epinastic Tomato Growth

Question

One variety of tomatoes in my new greenhouse has developed epinastic growth at the top of the plant. There are no herbicides anywhere around. We did use plywood on the inside walls. I also used Miracle Grow potting soil to pot the plants. I’m using the same soil for all the plants, so I would not think that is the problem. The variety of tomato that is affected is Beaver Lodge from Territorial seeds. I’ve grown them before and never had a problem. I’ve been using halide and sodium lights at night for both the light and as a heat source, but the tomatoes are not under the lights now. Any idea about what could be causing this problem?

Answer 1

One cause of epinastic growth is waterlogged soil, especially on tomatoes.
