Cucumber leaves curling downward
Comments (1)A photo of the leaves and plant will help immensely. Are the leaves actually curling or just drooping? Rodney...See MoreTomato leaves curling downward
Comments (9)I don't think it could be a caterpillar as there is no soil in my basement, and I am growing with aeroponics. Here are some more details and pictures. I am growing using aeroponics (low pressure). The plants are wilting from the bottom branches upwards. As each branch wilts and dies the next one up does the same. The leaves are also curling downards and curling in on themselves. The bottom most leaves are tough and leathery and have purple and yellow color. The main stem is purple near the bottom. The person at the hydroponics shop said that he believes my nutrient tank is getting too cold. I checked the temperature and its 70F during the day. I know the air temperature under the 400W HPS lamp remains around 74F during the day, but goes to about 64F at night. Lowest nightime air temperature in the last 30 days was 61F. I am uncertain what the temperature of the water (nutrients) goes down to at night time. I am growing these in my basement and the nutrient tank is sitting on the cold concrete floor of my basement. I have tried two different fertilizers and have grown the same tomatoes in deep water culture without issue using the same fertilizer. I have tried adding hydrogen perioxide to the nutrient water but it did not help. The roots are white and look healthly although the number of roots seems to be stunted as I would expect more roots after 30 days of growing than I am seeing. I have tried regrowing the same tomato plants several times and each time I have cleaned my system out completely, yet I still end up with the same issue. The only thing I can think of us that the water is getting too cold at night. I have my aeroponic sprayers running 1 minute on and 5 minutes off, 24/7. My 400W HPS lamp runs 16 hours on, 8 hours off each day. Running about 700PPM right now, ph is around 6.3. I have tried higher and lower nutrient levels and higher and lower ph levels which did not appear to help.

Comments (3)My tomato plants were harden off in the sun and were about 6 inches tall when I planted them in the ground. They were fine and were watered very well but after a few days we received a couple of days of rain. The main stem is getting larger but the plants are curling up as if the were rolling into a ball. They are south facing and are receiving full sunlight about 8 hours a day. Are they getting too much sun...See Moreyoung tomato plant leaves are small and curled downwards?
Comments (6)Looks like an ok plant to me. Different varieties have different characteristics and tendencies to curl. Tomato leaves are very cool. I haven't read this elsewhere but I think the tomato plant uses them as tendrils by just observing my own masses of leaves. Back to yours. There are many reasons a tomato plant can curl that have to do with environment, toxins and simply poor general fertilization rather than a single obvious deficiency. IMO, this picture does not contain enough enough info to really rule in or rule out many of them. I would be sure to not over water the plant and smother the oxygen loving roots, though, so that is my suggestion, though just general. Is that a 240 mL cup? It might be very small and each time you water it , iof there is no drainage as the plant reaches transplant size, is a big change of soil water, especially if it collects on the bottom. This can interfere with nutrient take up as well.. Good luck....See Morepelargonium_gw
