Q.tomatoes grown indoors in a large container
I have grown tomatoes this way for a few years now. This year my tomato leaves are a healthy dark green color but always look wilted. The leaves curl down, not up. I find no evidence of bugs or fungus. The container was new, the soil was a bagged garden mix also new and unopened. I start the seeds directly in the container. I do have a crop but it was later in coming and not as prolific as in the past. I am using the same variety of seed as in the past. It is a bush type. This year I added grown lights which I have on a timer for 8 hours a day. The plant room is a southwest facing room. My tomato plants least year were very prolific and the plants lasted over 9 months. I am also growing bell peppers, cukes and carrots with no problems. I use a water meter. Any idea what is happening/or not that is causing the plants to seem to have little turgor pressure in the leaves? The stems do not seem limp. Thank you
This is most likely Physiological Leaf Roll.
You can increase light and make sure the nutrient needs are met.
